Genome-wide study of hair color in UK Biobank explains most of the SNP heritability. Women take a higher percentage of red hair compared to men. Each persons DNA includes 20,000 genes. All rights reserved. Where do you find the most people with red hair and green eyes? Blonde-haired heads have more strands of hair than red- or dark-haired heads. and We explored the effect of including principal components (PCs) on the genetic correlation between hair and eye color. Isaacs, Aaron (2009). Thats followed by blonde hair. 20. bThe province of Flevoland consists of reclaimed land and did not yet exist in 1908. 52. Red hair is most commonly associated with Ireland. You might believe that because these genetic traits are rare, they could be diluted out of the gene pool entirely. (World Atlas), Green eyes occur in only 2% of the global population. According to an article by evolutionary biology professor . Biology dictates that the parents can pass down recessive, dominant, or both types of genes to their offspring. Gene characteristics fall into two categories: recessive and dominant. This was done by defining individuals on a specific platform as cases and the others as controls. So if that describes you, youre most likely one in a million (or more!). We recommend our users to update the browser. The GWAS for hair color in this sample was published previously (Lin et al., Reference Lin, Mbarek, Willemsen, Dolan, Fedko and Abdellaoui2015) and the results from the GWAS for eye color are described in the Supplementary material. This is due to the nature of brown genes being a dominant gene. A third of the men polled (33.1%) said they think the most attractive hair color is brown hair, while 28.6% said they prefer black hair. Nooren, Irene Always trying out the latest styles and trying to imitate her musical icons. They say beauty lies in the eye of the beholder, but in some cases, beauty thrives in whats unique. To view supplementary material for this article, please visit https://doi.org/10.1017/thg.2016.85. We have them for you if you want the latest hair color statistics. 1. Choi, Jiyeon Eye color results from the amount of pigment (melanin) you have in the front layer (stroma). Zhernakova, Dasha V. Schalkwijk, Casper G. And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings. van der Breggen, Ruud Hair Statistics: Anatomy of Hair Hair Care Industry Statistics 2022 Hair Discrimination Statistics Hair and Eye Color Combination Statistics Salon Industry Statistics in 2022 Share Sign up to our newsletter and get exclusive hair care tips and tricks from the experts at All Things Hair. Ricao-Ponce, Isis Uitterlinden, Andr G. This is not unexpected since hair and eye colors strongly indicate the ancestry of an individual. Finally, there is a clear and strong genetic overlap for brown eyes and a dark hair color. 26. This blend isnt as unique as the first one since green eyes are actually more common than blue eyes. However, some areas have dominating genes which can more likely than not increase the chances of getting this combination. That means youd need to inherit copies from both parents to have this color combination. However, this doesnt mean all people from Scandinavia have lighter eyes. (World Atlas), Between 8% and 10% of people worldwide have blue eyes. This indicates that the genetic PCs of the Dutch population are capturing the overlapping genetic variance of eye and hair colors. 200 . However, these PCs also capture multiple traits that likely underwent simultaneous genetic divergence between (sub)populations, such as eye and hair color. Li, Yang van Meurs, Joyce 19. van Galen, Michiel Due to genetic complexities, theres not a clear-cut way to determine your chances of having a child with both red hair and green eyes. The results confirmed the involvement of two genes, HERC2 and SLC24A4, in both hair color and eye color. Asians have black hair and black eyes. Red hair and green eye genes are simply not as common in populations as other hair and eye colors. (2016). Different levels of the pigment create the appearance of blue, brown, and everything in between. and Hair colors are a spectrum of hues ranging from white blond to coal black. The split by Sex was added by Friendly (1992a) for didactic purposes. van der Maarel, Silvere M. Like red hair, left-handedness is a recessive trait. While blonde hair is a recessive gene, it is not a disappearing gene. Melanocytes are melanin-forming cells in your skin. Koning, Frits MC1Rthe same gene that plays a large role in hair coloralso modulates pain sensitivity, Dr. Kaplan says. The best-studied hair-color gene in humans is called MC1R. Hair colors are passed down through generations. However, research also shows that Caucasian men have more blue eyes that any other group of people. Lepik, Kaido Since green eyes is not an origination factor affected by location, it can be seen in just about any person, as long as one or both parents have this recessive gene. Red hair: About 33% pheomelanin and approximately 66% brown or black eumelanin. 75-84% of the world's population has naturally black or dark-brown hair (depending on the study). Parents can also be carriers for recessive genes. Kutalik, Zoltn Thats why something like red hair or blue eyes could skip generations and show up a few steps down the family line. Sources: WebMD, You Probably Need a Haircut, LiveScience, NCBI, Statista, MedLine Plus, AiryHair. A review by medical daily explains that these two traits are recessive genes, therefore, reducing the number of individuals to extremely low. Skrypnik, Olga V. Theres a lot more to it than the simple dominant and recessive traits we learned about in high school biology. Genes provide the instructions for producing melanin. It has a correlation of -0.14 %, just slightly higher than red hair and blue eyes. 6. Learn about its uses, safety, and potential downsides here. Boomsma, Dorret I. After imputation, SNPs were filtered, based on Mendelian error rate (>2%), a R That is why the combination of amber eyes with brown hair is also rare. Other studies indicate more rare combinations such as amber eyes and blonde white hair. Heritability estimates for hair color range from 61% to 100%, and for eye color similar high estimates are obtained (Brauer & Chopra, 1980; Lin et al., 2015; Zhu et al., 2004 ). One possible exception: If you have a lighter skin tone (which is common in redheads), living closer to the equator could put you at greater risk for UV exposure and related skin cancers. 41. Xie, Sumei If so, your hair and eye color combination is among the worlds rarest. They have a fascinatingly high pain tolerance. Keep in mind that children with the same parents can have different eye and hair colors. The type and amount of melanin in the hair are determined by many genes, although little is known about most of them. (Cambridge University), Brown eyes with dark hair have a positive correlation of 0.71. Blue eye color in humans may be caused by a perfectly associated founder mutation in a regulatory element located within the HERC2 gene inhibiting OCA2 expression. The color of the human eye: A review of morphologic correlates and of some conditions that affect iridial pigmentation. The counts and frequencies of the hair and eye color phenotypes for the 3,619 individuals (1,401 males; age: 41.0419.81 and 2,218 females; age: 39.1317.17) are presented in Table 2(a), whereas Table 2(b) summarizes the information on the hair-eye color association from the much larger sample collected by Bolk (Reference Bolk1908), confirming the strong association in the Dutch population. Myths about people with red hair and green eyes. Slagboom, P. Eline Boomsma, D. I. Ye, Ke If one parent is redheaded and the other isnt, the chances their child will have red hair is about 50 percent, though the shade of red may vary greatly. How to Clean Every Room in Your Home: Smart Tips That Make Housecleaning Easier, Fasterand Done! van t Hof, Peter Franke, Lude DOI: Liem EB, et al. Dark brown eyes that resemble black eyes leaves the hair with a rich color and eyes to complement. According to current statistics, only around 5% of the people in this world have this hair and eye color combination. 32. 3. Beekman, Marian Redheads can generate their own vitamin D when they are exposed to low light environments. The observed value of the the 2 test statistic is 138.2925. Genetic determinants of hair, eye, and skin pigmentation in Europeans. Feature Flags: { Next, we added three Dutch PCs calculated from the genetic data (Abdellaoui et al., Reference Abdellaoui, Hottenga, de Knijff, Nivard, Xiao and Scheet2013) as covariates, to explore the effect of ancestry-informative PCs on the analysis, since hair and eye color are likely related to the population diversity captured by these PCs. You can learn more about how we ensure our content is accurate and current by reading our. Aguirre-Gamboa, Ral Sign up to our newsletter and get exclusive hair care tips and tricks from the experts at All Things Hair. PCs representing Dutch ancestry and geographic location are likely to explain the largest part of the variability of human pigment traits. Dark green eyes like emerald appear close to brown eyes which eliminates the uniqueness of this combination. As is evident from Table 1 using data from the Netherlands Twin Register collected around 2004, this is still the case roughly a 100 years later. 46. SNPs with a minor allele frequency (MAF) < 0.01 were also removed, as well as SNPs that were out of HardyWeinberg Equilibrium (HWE) with p < 105. The combination is subtle, warm, and well put together. DOI: Martinez-Cadenas C, et al. When it comes to hair and eye color, some genes are more dominant than others. See additional information. To understand that, we need to understand a bit of genetics. (2018). Blonde hair: About 33% pheomelanin and approximately 66% brown eumelanin (no black eumelanin). 9. The genetic correlation between the various dichotomous hair and eye color combinations (i.e., defined by whether a color was present or absent for the eyes and hair) was estimated using the GCTA bivariate analysis option (Lee et al., Reference Lee, Yang, Goddard, Visscher and Wray2012). Samples were excluded from the data when their DNA was discordant with their expected sex or IBD status, the genotype missing rate was above 10%, the Plink F-inbreeding value was either larger than 0.10 or smaller than 0.10, or they were an ethnic outlier based on EIGENSTRAT PCs calculated from the 1000G imputed data (Auton et al., Reference Auton, Brooks, Durbin, Garrison, Kang and Korbel2015). Very common with true Americans. There are other shades of eye color out there that havent yet been matched with the right hair color. Qiao, Shuo-Wang Well for these two traits; hair and eye color the genetic characteristic falls into the recessive form, which means it has to be passed done from the parent; both parents actually. van der Kallen, Carla J. H. 51. 31. Kluft, Cornelis 48. Bartels, M. Hottenga, Jouke J. Bonder, Marc Jan Genes also have variants, known as alleles. Still, not everyone from Ireland or everyone with an Irish bloodline will end up having red locks. "useRatesEcommerce": false Vermaat, Martijn Mao, Zhengsheng The genes involved in hair color also influence eye and skin color. The genetic overlap between hair and eye color. Is hair color determined by genetics? Veldink, Jan H. However, theres still a 50% chance of getting these combinations even if your parents dont have it as some individuals are carriers or could have alleles for this particular blend of recessive traits. and 21 Ash Brown Hair Looks Trending Right Now, 12 Peekaboo Highlights for 2023 and How to Get the Look, Hair and Eye Color Combination Statistics, Multi Colored Hair Ideas: Colorful Hairstyle Ideas for Pride and Beyond, 15 Honey Hair Color Ideas We Love, Plus How to Get the Perfect Shade of Honey for You, Money Piece Hair: Upgrade This trend for 2023, SheaMoisture Wig & Weave Tea Tree & Borage Seed Oil Flyaway & Wrap Mousse, Suave Essentials Refreshing Waterfall Mist Conditioner, Suave Professionals Anti-Dandruff 2-in-1 Dry Scalp Shampoo & Conditioner, 30 Ways to Wear Mocha Brown Hair Color this Spring, 15 Auburn Hair with Blonde Highlights to Elevate Your Look, 20 Shades of Brown Hair and How to Pick the Best for Your Skin Tone, 5 Stunning Ways to Wear Caramel Balayage Hair, 26 Ways to Wear Caramel Highlights on Different Hair Textures. Arindrarto, Wibowo Health status by gender, hair color, and eye color: Red-haired women are the most divergent. Ikram, M. Arfan So depending on which genes the parents have the child has zero to 100% chance of getting this unique combination. van Zwet, Erik W. 5. As for the brown eyes, 50 70 % of the global population had brown eyes. Here, we focus on the question whether all genes affecting one of these visible traits also affect the other trait. van Greevenbroek, Marleen M. J. Suchiman, H. Eka D. Zhernakova, Alexandra van der Breggen, Ruud Redheads can't absorb . That means 0.17 percent of the world's population, or roughly 13 million people, have this hair and eye color . Black/dark brown hair is the world's most common hair color. Close this message to accept cookies or find out how to manage your cookie settings. Boomsma, Dorret I. Boomsma, Dorret I. Hair and eye color are two major features in determining an individual's appearance within a population. Another fun fact about redheads? While its slightly easier to determine the odds of having red hair, green eyes are more difficult to predict. (2005). Shelf Life & Reading Expiration Dates, Does Honey Lighten Hair? van Meurs, Joyce Red hair, light skin, and UV-independent risk for melanoma development in humans. Hannon, Eilis Just a few of these genes dictate hair color and eye color. Other common hairs and eye combinations include; This is a blend that others claim is overrated. For example, the MCR1 gene comes in two variants: non-red and red. This is a classic combination for all those light to dark brown-haired people. This gene is responsible for their hair but also their skin color as it determines their skin pigmentation. Red hair and green eyes are the rarest hair and eye combination. Require More Anesthetic Redheads may be harder to sedate than blondes or brunettes, and require more anesthesia during surgery. 10. t Hoen, Peter-Bram Moed, Matthijs Waldenberger, Melanie According to Julie Kaplan, MD, a physician at the Cleveland Clinics Center for Personalized Genetic Healthcare, your hair color in particular is tied to variations in a specific gene. 28. Lugovnjov, Artur V. This study was supported by multiple grants from the Netherlands Organization for Scientific Research (NWO: 016-115-035, 463-06-001, 451-04-034), ZonMW (31160008, 911-09-032); Institute for Health and Care Research (EMGO+) and Neuroscience Campus Amsterdam (NCA); Biomolecular Resources Research Infrastructure (BBMRINL, 184.021.007), European Research Council (ERC-230374); Biobanking and Biomolecular Resources Research Infrastructure (BBMRI-NL: 184.021.007). van Iterson, Maarten Both hair and eye color are determined by gene variants present in the melanin pathway, including HERC2/OCA2, SLC24A4, and TYR (Candille et al., Reference Candille, Absher, Beleza, Bauchet, McEvoy and Garrison2012; Liu et al., Reference Liu, van Duijn, Vingerling, Hofman, Uitterlinden and Janssens2009; Sulem et al., Reference Sulem, Gudbjartsson, Stacey, Helgason, Rafnar and Magnusson2007; Zhang et al., Reference Zhang, Song, Liang, Nan, Zhang and Liu2013), though these genes may not explain all genetic variance in hair and eye color. Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent. A smaller percentage of humans, approximately 0.17 percent or 13 million, have a combination of red hair and blue eyes. 2022. We identified the genetic variants for eye color by Genome-Wide Association Study (GWAS) in a Dutch Caucasian family-based population sample and examined the genetic correlation between hair and eye color using data from unrelated participants from the Netherlands Twin Register. Even so, green-eyed individuals are much more common nowadays. Last medically reviewed on June 24, 2020. (2004). Genotyping was made possible by grants from NWO/SPI 56-464-14192, Genetic Association Information Network (GAIN) of the Foundation for the National Institutes of Health, Rutgers University Cell and DNA Repository (NIMH U24 MH068457-06), the Avera Institute, Sioux Falls (USA) and the National Institutes of Health (NIH R01 HD042157-01A1, MH081802, Grand Opportunity grants 1RC2 MH089951 and 1RC2 MH089995). Hence, even when combined with red hair genes, which is a recessive allele, the offspring will still have brown hair. This data set is useful for illustrating various techniques for the analysis of contingency tables, such as the standard chi-squared test or, more generally, log-linear modelling, and graphical methods . 8. Though about 1-2% of the general world population has the red hair gene, that percentage rises to 2 to 6 percent north of the equator. Porcu, Eleonora Claringbould, Annique 2023 Healthline Media LLC. The combination of red hair and blue eyes is the rarest color combination of all for human beings. der Breggen, Ruud van This is because they naturally have lower melanin concentration. The likelihood of this happening is quite rare, especially if neither of your parents has red hair or blue eyes. The chances you or your child will have it are based on whether your immediate family members had red hair or green eyes, though it can skip generations. In the Western hemisphere, 10 to 15 percent of people use their left hand dominantly. Swertz, Morris A. It can cause infertility and other symptoms. The most common hair and eye combination for such is brown hair with brown eyes. If they only have one of the three variants, there is still a greater chance of red hair, though they may be more likely to have strawberry blond. According to an American Academy of Ophthalmology survey, green eyes are the rarest. Purely categorical data can be. Luijk, Ren The genes responsible for hair color arent dominant or recessive. After spending 6 further years learning her trade in different salons across the country, she went on to finally live her dream of opening her own. This statistic is a powerful reminder of the uniqueness of the red hair and blue eyes combination. The non-red version is dominant. Red hair is more common in women, according to research. 34. Hacks & Inspiration from Hair Experts at Unilever. van Duijn, Cornelia M. 11% of the worlds population have brown hair color. The combination is captivating and alluring to have light to medium brown hair matched with bright colored eyes. van Dijk, Freerk Red hair is the hardest to dye. Most articles youll read about green eyes, you will also note that they pair very well with brown hair. Relton, Caroline Kielbasa, P. Szymon M. In our study, we only selected European Caucasian individuals based on the genetic PC projection and 1,000 genomes. But from 1936 to 1951, that number fell to 33.8 percent. Wijmenga, Cisca Wijmenga, Cisca as.data.frame converts cross-tabulated data to . Lakenberg, Nico You can imagine a natural blonde like Drew Barrymore with amber eyes. In Africa, 1.2 billion people have black hair color. Due to the low prevalence of red hair color in our population, we do not detect any significant genetic overlap with any eye color. For example, if both parents have red hair, a child receives mostly the genetic information for red hair, so the chances they will have red hair is almost 100 percent. Mill, Jonathan The degrees of freedom is = (4 1)(4 1) = 9. Heijmans, Bastiaan T. Blue eyes are similarly uncommon, and they may be becoming rarer. van Greevenbroek, Marleen M. J. Uitterlinden, Andr G. For eye color, the OCA2 gene determines how much melanin is in the iris (the colorful ring around your pupil) by controlling how much P protein is produced. Red hair with green/hazel eyes showed the weakest correlation (-0.14). There are 27 contract manufacturers of hair coloring products in the United States, mostly based in New Jersey. Real-life Examples: Jennifer Connelly, Demi Moore, Megan Fox, Rihanna. In fact, redheads have some other rare tendencies. DOI: Mengel-From J, et al. Hair and eye color are two major features in determining an individual's appearance within a population. 9. A pigment called melanin determines our hair, eye, and skin color. For example, alleles of the gene OCA2 determine whether someone has brown or not-brown eyes. Black hair has multiple shades and undertones. Scotland has the highest population of redheads in the world, coming at 13%. The phased data were then imputed with MINIMAC to the 1000G reference. Pool, Ren Vakula, Svetlana I. Boomsma, Dorret I. Mei, Hailiang There were 7,063 genotyped Dutch-ancestry participants, clustered in 3,407 families with data on eye color, and 6,965 genotyped individuals had data on both hair and eye color. Red hair is the rarest hair color, with only 1% of the worlds population having this hair shade. Genetics plays a huge role in just how rare some of these combinations are. Li, Kai Gey, one of the genes determining eye color, comes in two forms: green and blue. 27% with blue . Yu, Yanfang 5. 24. For example, redheads are mostly found in Scotland, Ireland, and parts of Great Britain. While redheads are born all throughout the world, theyre more likely to crop up in the Northern hemisphere. (Rarest), 1% to 2% of the worlds population has red hair. Tigchelaar, Ettje F. Lets have a look at interesting facts about them; Blondhairis identified by low levels of the darkpigmenteumelanin. Having a nice blonde hair means your facial features are already lighter just by having almost white hair. Light hazel is the lightest form of brown eyes, just very bright when reflected on the sun. The genetic correlations between the hair and eye colors are presented in Table 3. Blue eyes contain much less melanin than brown eyes. cross-tabulated. Verbiest, Michael Liem EB, et al. Our virtual concierge will create a hair care regimen just for you. Data Formats. However, the natural blend is harder to acquire since the number of true blondes is slightly under 10% of the global population. As can be easily observed that there is a great variety among redhead people. Hair and Eye Color Combination Statistics Only 0.17% of the world has blue eyes and red hair, making it the rarest hair and eye color (University of Melbourne) Green eyes and red hair are the second rarest combination, with one study finding red hair with green or hazel eyes has a weak correlation at -0.14. Participants in the Netherlands Twin Register (van Beijsterveldt et al., Reference van Beijsterveldt, Groen-Blokhuis, Hottenga, Franic, Hudziak and Lamb2013; Willemsen et al., Reference Willemsen, Vink, Abdellaoui, den Braber, van Beek and Draisma2013) were included in this study based on the presence of self-reported data on natural hair and eye color and the presence of genotype data on an Illumina 370, 660, 1M or Affymetrix Perlegen-5.0, or 6.0 platform. Mei, Hailiang The more melanin you produce, the darker your eyes, hair and skin will be. Beekman, Marian Jansen, Rick Min, Josine L. Mei, Hailiang Red hair, occurring in just 1 to 2 percent of the population, is the least common. According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color. 2023 Healthline Media LLC. According to a 2018 study published in Nature, the OCA2 gene, which is important for eye color, also interacts with the MC1R gene and can reduce your likelihood of having red hair. (BBC), Only a little over 3% of the worlds population are a natural blonde. Gene therapy can treat certain genetic conditions by editing diseased cells. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Although the overall pigmentation prevalence has changed during the past 100 years (see Table 1: hyper-pigmentation traits are more prevalent in 2004), the distribution pattern of pigment traits following latitude is still the same. van Zwet, Erik W. When adding the first three genetic PCs that correlated with Dutch ancestry, the genetic correlations are reduced to zero (LRT = 0, p value = .5). Peyton, Shanna A. van Rooij, Jeroen Zhang, Beilei Blue eyes, on the other hand, are more common: About eight percent of the world population has blue eyes. And its not just because of MC1R. Uitterlinden, Andr G. Jansen, Rick Tigchelaar, Ettje F. Blonde hair can range from practically white (platinum blonde) to a dark golden blonde. Franke, Lude 51 Homecoming Prom Hairstyles for Girls with Short Hair, Only 0.17% of the world has blue eyes and, Green eyes and red hair are the second rarest combination, with one study finding red hair with green or hazel eyes has a weak correlation at -0.14. Zhernakova, Dasha V. The number of people with brown hair is relatively small. t Hoen, Peter A. C. Theres a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. Cao, Yue DOI: Frost P, et al. van den Berg, Leonard H. Phasing of the samples and imputing cross-missing platform SNPs was done with MACH 1 (Li & Abecasis, Reference Li and Abecasis2006). Sanna, Serena van Heemst, Diana Yang, Jiawen Your IP: vanDijk, Freerk Written informed consent was obtained from all participants. In populations where more people have the not-brown OCA2 allele like in Scandinavia the allele for light eyes is more common, even though its recessive. Low levels of both eumelanin and phaeomelanin characterize blonde hair. vanGalen, Michiel Norway, Sweden, Denmark, Iceland, and Finland have the highest blonde hair rates. Gudievskaya, Irena G. That means that in total, 59.7% of men said they. Bot, Jan Heijmans, Bastiaan T. DNA methylation refers to the process of adding a methyl group to one of the bases of your DNA. This website is using a security service to protect itself from online attacks. Kallsen, Noah A. Claringbould, Annique Both parents can display recessive gene characteristics, and they can pass those to their children, too. Hair color is determined by pigment or melanin in the hair. Survey of Ophthalmology , 41 (Suppl 2), S117-123 https://www.ncbi.nlm.nih . Zhernakova, Alexandra Almost everyone (even people with blue or green eyes) has brown pigment in the back layer of the iris. Keep reading to learn what the rarest hair and eye color combinations are, plus other tidbits of information, including facts about redheads. Luijk, Ren Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Daxinger, Lucia Deng, Chuwei Suchiman, H. Eka D. Schalkwijk, Casper G. The MCR1 gene comes in two variants: non-red and red. (Cambridge University) Hostname: page-component-789cc574b8-jngkm 2. Westra, Harm-Jan To address this question, we estimated the genetic correlation between hair and eye color for common single nucleotide polymorphisms (SNPs) within a sample from the Dutch population using genomic restricted maximum likelihood (GREML) estimation for bivariate analyses (Lee et al., Reference Lee, Yang, Goddard, Visscher and Wray2012) as implemented in the Genome-wide Complex Trait Analysis (GCTA) software package (Yang et al., Reference Yang, Lee, Goddard and Visscher2011). She studied hairdressing directly after leaving school, spending 2 years at college learning from the best hairdressers in her region. Red hair is rare because its a recessive trait that occurs only when a person has 2 copies (one from each parent) of a mutated melanin-conversion (pigment changing) gene. Zhan, Wenxuan Verbiest, Michael van Heemst, Diana count from dplyr produces aggregated data from raw data. 29. This in total leaves an estimate of 65 to 75% of the worlds population with brown hair and brown eyes. Nivard, M. G. 33. For the statistical analyses, we combined the black, light brown, and dark brown hair colors to dark, as only very few people reported a black hair color (Lin et al., Reference Lin, Mbarek, Willemsen, Dolan, Fedko and Abdellaoui2015). Kielbasa, P. Szymon M. If one person has both red hair and blue eyes, theres a good chance one or both of their parents do, too, but not always. Jansen, Rick 23. Brown to also mean brunettes. 15. Hair And Eye Color Combination Statistics Overview The rarest hair and eye color combination is red hair with blue eyes, occurring in less than 1% of the global population. Franke, Lude Jansen, Rick 53. Yet dominant doesnt necessarily mean more common. Millions of unique hair color shades people wear around the world. The strongest positive correlations were found for blue eyes with blond hair (0.87) and brown eyes with dark hair (0.71), whereas blue eyes with dark hair and brown eyes with blond hair showed the strongest negative correlations (-0.64 and -0.94, respectively). (2016). Swertz, Morris A. Stehouwer, Coen D. A. How common is it for someone to have red hair and blue eyes? Tigchelaar, Ettje F. )(new Image()).src = 'https://capi.connatix.com/tr/si?token=38cf8a01-c7b4-4a61-a61b-8c0be6528f20&cid=877050e7-52c9-4c33-a20b-d8301a08f96d'; cnxps.cmd.push(function () { cnxps({ playerId: "38cf8a01-c7b4-4a61-a61b-8c0be6528f20" }).render("6ea159e3e44940909b49c98e320201e2"); }); Hair color is a bit more complex than dominant and recessive and is related to variants in the MC1R gene, says Dr. Kaplan. (Readers Digest), Between 55% and 79% of the worlds population has brown eyes. At least three different genes control eye color, and there can be more than two alleles for each gene. Whats more fascinating is that there more to it than just the unique color of the hair, its the hair and eye combinations. Chen, Peng Anesthetic requirement is increased in redheads.
