It is important to realize when studying eye and hair color that these phenotypes can be highly correlated with the genetic constitution of the population. van Greevenbroek, Marleen M. J. PCs representing Dutch ancestry and geographic location are likely to explain the largest part of the variability of human pigment traits. Even so, there are still genetic complexities that make it hard to dictate these traits for your offspring. 55. Deelen, Joris When MC1R is inactivated, the body produces more pheomelanin, which is responsible for reddish skin and hair tones, than eumelanin, which is responsible for shades of brown and black. Mandaviya, Pooja Aguirre-Gamboa, Ral The most common hair and eye combination for such is brown hair with brown eyes. Do you have red hair or green eyes? vanRooij, Jeroen 75% of American women dye their hair today. If you have the rarest hair and eye color combination, you're one in a millionor more!If you have dark brown hair and brown eyes, you have something in common with most people around the globe. Having red hair and blue eyes is even rarer. Low levels of both eumelanin and phaeomelanin characterize blonde hair. Among these identified pigment genetic variants, we detected that HERC2 has pleiotropic effects on blond, brown, dark hair color and blue/gray, brown eye color, and SLC24A4 has pleiotropic effects on blond, brown, dark hair color and blue/gray and green/hazel eye color. Keep in mind that children with the same parents can have different eye and hair colors. That means 0.17 percent of the world's population, or roughly 13 million people, have this hair and eye color . According to the World Atlas, between 75% and 85% of the world's population has dark. (2007). AIS is an intersex variation found in males who are resistant to male sex hormones. Verbiest, Michael Arindrarto, Wibowo Always trying out the latest styles and trying to imitate her musical icons. Black/dark brown hair is the world's most common hair color. Less than 1 in every 20,000 people worldwide have piebaldism disorder. (The lack of melanin also puts redheads at a higher risk for skin cancer. DOI: Martinez-Cadenas C, et al. Jhamai, Mila 15. Only 2% of people in the world are natural blondes. That makes the blue eye and red hair combination even more unlikely to happen. What determines your hair, eye, and skin color is a pigment called melanin. Bonder, MarcJan We tested the effect of different platforms and removed SNPs showing platform effects. The United States has the second largest natural redheads population, around 5%. van den Berg, Leonard H. If the allelic association between the specific platform allele frequency and the other platform's allele frequency was significant (p < 105) SNPs were removed. Is handedness determined by genetics? Gingers generate their own Vitamin D. Having pale skin may mean that redheads burn more easily when exposed to UV rays, but their paleness can serve as an advantage. However blue eyes, still require the recessive gene present so as to pass it on to an offspring. t Hoen, Peter A. C. Luijk, Ren 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. The combination is captivating and alluring to have light to medium brown hair matched with bright colored eyes. t Hoen, Peter A. C. Its all thanks to a single gene. Jonkers, Iris (2005). The best way to predict a childs genetic makeup is to look at each parents genes. Jansen, Rick The platform data were then merged into a single genotype set and the above SNP QC filters were reapplied. Boomsma, Dorret I. Here, we focus on the question whether all genes affecting one of these visible traits also affect the other trait. Red hair and green eye genes are simply not as common in populations as other hair and eye colors. Around 17 percent of people have blue eyes, and when combined with 1-2 percent having red hair, the odds of having both traits are arund 0.17 percent. Veldink, Jan H. (2017). Dekkers, Koen F. Brown, Kevin M. Blondes make up about five percent of the world population, just three percent higher than redheads. Theres a higher ratio of blondes in your everyday life than the official 2-3% natural blonde statistic. 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). Rimbert, Antoine Richardson, Tom G. Redheads can generate their own vitamin D when they are exposed to low light environments. Carnero-Montoro, Elena Red hair, light skin, and UV-independent risk for melanoma development in humans. In such a case one can only notice the blue in the eyes once sun or bright light is reflected in the eyes, therefore, the eyes seem dull and uncannily dark compared to the true blue color. Other studies indicate more rare combinations such as amber eyes and blonde white hair. This year, the hair color industry is booming, especially after the Covid-19 pandemic lockdown. Koning, Frits (2018). Yet dominant doesnt necessarily mean more common. Arindrarto, Wibowo When conducting gene finding studies or GCTA analyses, researchers should therefore be aware of the effects of ancestral population differences on the relationship between stratified traits. The genes involved in hair color also influence eye and skin color. Hofman, Bert A. Note: aThis variable is Blond hair + blue eyes in the 1908 data and Blond hair + blue/gray eyes in the 2004 data. It can cause infertility and other symptoms. Mill, Jonathan The MCR1 gene dictates whether you have red hair and is recessive. (2016). Redheads more often than not have a European ancestry either northern or western. 37. Fedko, I. van Zwet, Erik W. In fact, redheads have some other rare tendencies. According to an article by evolutionary biology professor . Your IP: Red hair and green eyes are the rarest hair and eye combination. Are redheads with blue eyes really going extinct? When including the first three PCs as covariates, the genetic correlations between the phenotypes disappeared. Dekkers, Koen F. 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. But thats a simplistic view of eye color, and determining hair color is even more complex. Close this message to accept cookies or find out how to manage your cookie settings. (Cambridge University), The strongest negative correlations for hair and color combination to be blue eyes with dark hair (-0.64) and brown eyes with blonde hair (-0.94). 12. 17. Last medically reviewed on June 24, 2020. These are just but a few of scientific wonders that has people hoping to see even once in their lifetime. van der Breggen, Ruud (2010). What are the rarest hair and eye color combinations? One study found that between 1899 and 1905, more than half of non-Hispanic white people in the United States had blue eyes. 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. Still, the combination of red hair and green eyes tends to be uncommon in todays population. What do the hair and eye color statistics tell about the makeup of the worlds color palette? Blue eyes are similarly uncommon, and they may be becoming rarer. Santoni, Federico A. Schalkwijk, Casper G. A person's eye color reflects a unique combination and concentration of pigments in the iris. Precisely, individuals with red hair are the least common with less than two percent of the global population. and As of 2019, over 64 million people used hair coloring products on their hair. Hannon, Eilis Ward-Caviness, Cavin K What about gender disparities? van Beijsterveldt, Catharina E. M. Only three variants are associated with red hair, she says. Knowing which genes play a role in hair and eye color variation can help us understand why some hues are more common than others. 47. Another pigment, called pheomelanin, gives people red hair. When a person has a child, they can pass their recessive gene information to their offspring, and the trait could win out. Genetic variations associated with red hair color and fear of dental pain, anxiety regarding dental care, and avoidance of dental care. (2018). Liem EB, et al. This left 5,987,253 SNPs, which were all used to construct a GRM. 56. 27. Genes provide the instructions for producing melanin. Last medically reviewed on September 18, 2018. Bolk (Reference Bolk1908) reported in an article that early in the 20th century in the Netherlands, the northern part of the country was characterized by more blond hair and lighter eye color than the southern part of the country. Vakula, Svetlana I. Red hair, occurring in just 1 to 2 percent of the population, is the least common. DOI: White D, et al. van der Maarel, Silvere M. Well explore how this process effects gene expression, At-home DNA testing kits can reveal so much about one's heritage and background. How to Clean Every Room in Your Home: Smart Tips That Make Housecleaning Easier, Fasterand Done! One study found that between 1899 and 1905, more than half of non-Hispanic white people in the United States had blue eyes. DNA methylation refers to the process of adding a methyl group to one of the bases of your DNA. vant Hof, Peter 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. Borek, Zuzanna Veldink, Jan H. Keep reading to learn what the rarest hair and eye color combinations are, plus other tidbits of information, including facts about redheads. Both hair and eye color are highly heritable. 3 in 4 Caucasian women choose to dye their hair blonde at some point in their lives. vanHeemst, Diana DNA Methylation: Can Your Diet Reduce Your Risk of Disease? Both parents can display recessive gene characteristics, and they can pass those to their children, too. (Cambridge University) The phenotypic association of eye and hair colors confirms the two traits to be strongly related in our sample ( Sources: WebMD, You Probably Need a Haircut, LiveScience, NCBI, Statista, MedLine Plus, AiryHair. Pairo-Castineira, Erola We've rounded up the best kits and details about each so you can. 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. Redheads know their hair color isnt the only unique characteristic. The color of your eyes relies on the pigment melanin, the same pigment that's in your skin and hair. Blonde hair: About 33% pheomelanin and approximately 66% brown eumelanin (no black eumelanin). The MCR1 gene dictates whether you have red hair, and its recessive. Even so, various factors come into play when discussing commonalities. 2-test with 4 degrees of freedom gave a p value < 2.21016): people with blond and red hair are likely to have blue/gray eyes while people with dark hair are more likely to have brown eyes. Parra, Esteban J. 2022. Next up is red hair and green eyes. The genetic combination of blonde hair and green eyes takes place once the haploid chromosomes from your parents happen to be exactly the same, therefore you inherit these polygenetic genes. Uitterlinden, Andr G. 32. Your Guide to Gene Therapy: How It Works and What It Treats, Your Guide to Androgen Insensitivity Syndrome (AIS), easier bruising, which may be linked to fairer skin tone making injuries more noticeable, a bad temper (hence the stereotype of having an Irish temper), a longer lifespan (for people with green eyes). There are 27 contract manufacturers of hair coloring products in the United States, mostly based in New Jersey. 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 . Lastly, if both parents are carriers of the gene variant but dont have red hair, the child has about a 1 in 4 chance of having truly red hair. Binkley CJ, et al. It depends on whether genes are turned on or turned off. Weihs, Antoine Kielbasa, P. Szymon M. } (2017). With the Genome-wide Complex Trait Analysis software package, we found strong genetic correlations between various combinations of hair and eye colors. However, Caucasian males are more likely to have blue eyes than females, research shows. Li, Kai It can cause infertility and other symptoms. 3. Franke, Lude The other six variants can lead to a range of blond to brown hair color.. This gene is responsible for their hair but also their skin color as it determines their skin pigmentation. This statistic is a powerful reminder of the uniqueness of the red hair and blue eyes combination. Liu, Qingfan Still, not everyone from Ireland or everyone with an Irish bloodline will end up having red locks. Blue eyes, on the other hand, are more common: About eight percent of the world population has blue eyes. Genetic determinants of hair, eye, and skin pigmentation in Europeans. Green eyes are rare, but so are blue eyes, red hair is even rarer compared to straight blondes. This in total leaves an estimate of 65 to 75% of the worlds population with brown hair and brown eyes. Theres HERC2, a gene that controls how the OCA2 gene works, essentially turning P protein production on and off. This medical condition, and perhaps others, seems facilitated by the combination of being red-haired and female. The Genetic Overlap Between Hair and Eye Color, Netherlands Twin Register, Department of Biological Psychology, Vrije Universiteit, Amsterdam, the Netherlands, Avera Institute for Human Genetics, Avera McKennan Hospital & University Health Center, Sioux Falls, South Dakota, USA, Reference Lin, Mbarek, Willemsen, Dolan, Fedko and Abdellaoui, Reference Zhu, Evans, Duffy, Montgomery, Medland and Gillespie, Reference Kayser, Liu, Janssens, Rivadeneira, Lao and van Duijn, Reference Posthuma, Visscher, Willemsen, Zhu, Martin and Slagboom, Reference Candille, Absher, Beleza, Bauchet, McEvoy and Garrison, Reference Liu, van Duijn, Vingerling, Hofman, Uitterlinden and Janssens, Reference Sulem, Gudbjartsson, Stacey, Helgason, Rafnar and Magnusson, Reference Zhang, Song, Liang, Nan, Zhang and Liu, Reference Lee, Yang, Goddard, Visscher and Wray, Reference Yang, Lee, Goddard and Visscher, Reference Abdellaoui, Hottenga, de Knijff, Nivard, Xiao and Scheet, Reference Beleza, Santos, McEvoy, Alves, Martinho and Cameron, Reference van Beijsterveldt, Groen-Blokhuis, Hottenga, Franic, Hudziak and Lamb, Reference Willemsen, Vink, Abdellaoui, den Braber, van Beek and Draisma, Reference Auton, Brooks, Durbin, Garrison, Kang and Korbel, Reference Howie, Fuchsberger, Stephens, Marchini and Abecasis, Reference Purcell, Neale, Todd-Brown, Thomas, Ferreira and Bender, Reference Han, Kraft, Nan, Guo, Chen and Qureshi, Reference Liu, Wollstein, Hysi, Ankra-Badu, Spector and Park, Population structure, migration, and diversifying selection in the Netherlands, A global reference for human genetic variation, The timing of pigmentation lightening in Europeans, Heeft roodharigheid de beteekenis van nuance of varieteit, Nederlands Tijdschrift van de Geneeskunde, Estimating the heritability of hair color and eye color, Genome-wide association studies of quantitatively measured skin, hair, and eye pigmentation in four European populations, A genome-wide association study identifies novel alleles associated with hair color and skin pigmentation, Fast and accurate genotype imputation in genome-wide association studies through pre-phasing, Three genome-wide association studies and a linkage analysis identify HERC2 as a human iris color gene, Estimation of pleiotropy between complex diseases using single-nucleotide polymorphism-derived genomic relationships and restricted maximum likelihood, Mach 1.0: Rapid haplotype reconstruction and missing genotype inference, Heritability and genome-wide association studies for hair color in a Dutch twin family based sample, Eye color and the prediction of complex phenotypes from genotypes, Digital quantification of human eye color highlights genetic association of three new loci, Replicated linkage for eye color on 15q using comparative ratings of sibling pairs, PLINK: A tool set for whole-genome association and population-based linkage analyses, Genetic determinants of hair, eye and skin pigmentation in Europeans, The young Netherlands twin register (YNTR): Longitudinal twin and family studies in over 70,000 children, The adult Netherlands twin register: Twenty-five years of survey and biological data collection, GCTA: A tool for genome-wide complex trait analysis, Genome-wide association studies identify several new loci associated with pigmentation traits and skin cancer risk in European Americans, A genome scan for eye color in 502 twin families: Most variation is due to a QTL on chromosome 15q, The Distribution (in %) of Hair Color and Eye Color Across Dutch Provinces in the 1908 Sample Collected by Bolk (, Hair and Eye Color Counts and Percentages for Unrelated Genotyped Individuals of the Netherlands Twin Register, Hair and Eye Color Counts and Percentages From Blom 1908, The Genetic Correlations Between Hair and Eye Color Estimated From Common SNPs (MAF > 0.01) Covering the Full Genome, Corrected for Age and Sex, Within Unrelated Individuals of the Netherlands Twin Register. Redheads with blue eyes form the rarest hair combo in the world. After imputation, SNPs were filtered, based on Mendelian error rate (>2%), a R A small percentage of people have unique blends such as red hair and blue eyes, or blonde hair and green eyes. Genotype-phenotype associations and human eye color. vanDijk, Freerk Gey, one of the genes determining eye color, comes in two forms: green and blue. The data came from unrelated individuals (N = 3,619) registered with the Netherlands Twin Register, which includes participants from all regions of the Netherlands. 5. 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. Blond hair is more expensive and will cost up to 3x more than dark hair. Myths about people with red hair and green eyes. We also conducted a GWAS for each of the two traits in the NTR population (see Lin et al., Reference Lin, Mbarek, Willemsen, Dolan, Fedko and Abdellaoui2015, for hair color and Supplementary material for eye color). DOI: Mengel-From J, et al. Tigchelaar, Ettje F. 46. Today,. Its also possible to get more information via genetic testing. Red hair is associated in women with pain sensitivity. That's 13 million people, out of the 7.6 billion on Earth. Find out why they appear and what to do if you don't want them. Blue is the dominant allele. The combination is subtle, warm, and well put together. and 2020. As with any uncommon trait, myths about certain hair and eye colors abound, especially on the internet. Brown hair comes in as the second-most common hair color in the world, with 11% of the population being naturally brunette. Data that includes categorical and numerical variables is usually in raw form. DOI: Liem EB, et al. Verkerk, Marijn All the facts about hair you were looking for. In addition, with both red hair and blue eyes being something akin to recessive traits, having parents that are able to pass on two sets of recessive genes is very unlikely. 9. 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. This indicates that the genetic PCs of the Dutch population are capturing the overlapping genetic variance of eye and hair colors. Blonde women are more susceptible to age-related macular degeneration (AMD), an eye condition that can cause blindness, Blondes produce less melanin, which leaves their skin more susceptible to skin cancer, Scientists believe that blonde hair evolved in sun-deficient climates so that the body could synthesize vitamin D more efficiently. Here, the same relation is shown as in the phenotypic description of the data, where the genes related to blond hair show a strong positive correlation with blue/gray colored eyes and a negative correlation with brown and green colored eyes. The iris has two layers. Lakenberg, Nico The possibility of such a combination means someone has this carried gene through hereditary cells. Scotland has the highest population of redheads in the world, coming at 13%. 11. The MCR1 gene comes in two variants: non-red and red. Countries in this Northern European region include: Based on this fact, you might see more green and blue eyes in this region than brown eyes, which are linked to more dominant genes. This is due to the nature of brown genes being a dominant gene. For the genetic association analysis of eye color (see Supplementary material) all data were analyzed. The true pattern of inheritance of hair color is somewhat more complicated, though, as there are many genes involved. White hair is characteristic of aging, but colorless hair strands can appear at any age even while you're still in high school or college. By the way, which one is itblond or blonde? Kooy-Winkelaar, Yvonne Wijmenga, Cisca (2018). (2002). All analyses were corrected for age and sex, and we explored the effects of correcting for principal components (PCs) that represent ancestry and describe the genetic stratification of the Netherlands. Ji, Qiang Where do you find the most people with red hair and green eyes? Boomsma, Dorret I. van Dijk, Freerk But what tops the list is red hair and blue eyes. Vsa, Urmo Zhernakova, Dasha V. The genetic overlap between hair and eye color. In redheads in particular, the MC1R gene doesnt function the correct way and causes these cells to make mostly pheomelanin, which is barely present in any of the other hair colors. 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. Redheads may drastically reduce in the future due to their unique genes. In Africa, 1.2 billion people have black hair color. Being recessive or dominant has nothing to do with whether or not a trait is common. Veldink, Jan H. For example, redheads are mostly found in Scotland, Ireland, and parts of Great Britain. Our DNA has 20,000 genes. (2013). and Health status by gender, hair color, and eye color: Red-haired women are the most divergent. Your parents passed these genes down to you, just as their parents passed down their genetic makeup to them. That means that in total, 59.7% of men said they. Zorro, Maria M. van der Kallen, Carla J. H. You can email the site owner to let them know you were blocked. (2011). Porcu, Eleonora The amount and type of melanin your body produces determines how dark or light your skin will be. The p-value based on the asymptotic 2 Women take a higher percentage of red hair compared to men. Reymond, Alexandre Hair coloring makes up 13% of the American hair care industry. Save my name, email, and website in this browser for the next time I comment. But from 1936 to 1951, that number fell to 33.8 percent. Very little eumelanin gives people blonde hair. Arindrarto, Wibowo Hacks & Inspiration from Hair Experts at Unilever. 172.104.46.201 Need some help with your hair color? China and India have the highest black and brown hair rates. Dark green eyes like emerald appear close to brown eyes which eliminates the uniqueness of this combination. Wu, Maowang Feature Flags: { Likelihood ratio Bell, Jordana T. Hair coloring reached over 29 billion U.S. dollars in 2019 globally. 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). Claringbould, Annique While the odds of having red hair and green eyes depends on a variety of factors, its interesting to look at the genetics behind this combination. 4. So what are the rarest hair and eye color combinations? Black Hair and Green Eyes. That is why the combination of amber eyes with brown hair is also rare. Bonder, Marc Jan Phasing of the samples and imputing cross-missing platform SNPs was done with MACH 1 (Li & Abecasis, Reference Li and Abecasis2006). Kielbasa, P. Szymon M. That means youd need to inherit copies from both parents to have this color combination. Only 3% of the world's population has natural blonde hair. Nooren, Irene The hair, skin, and eye colors youre born with are all controlled by your genes. This was done by defining individuals on a specific platform as cases and the others as controls. Jhamai, P. Mila Lucia Prinzi | September 16, 2022 Share Hair Color Statistics Hair and Eye Color Combination Statistics Hair Coloring Statistics 2021 Hair Color Statistics by Country Share van Meurs, Joyce van Zwet, Erik. TABLE 1 The Distribution (in %) of Hair Color and Eye Color Across Dutch Provinces in the 1908 Sample Collected by Bolk (N=480,165) and for the 2004 Survey in Adult NTR Participants (N=7,661). 54. Gudievskaya, Irena G. Zhernakova, Alexandra 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. 20 Common Hair Myths That Are Ruining Your Hair, Do Not Sell or Share My Personal Information. Deelen, Joris Heijmans, Bastiaan T. Learn about its uses, safety, and potential downsides here. Jansen, Rick Asians have black hair and black eyes. Both hair and eye color are highly heritable. So whats the rarest eye color? Bartels, Meike 2021. van der Graaf, Adriaan Redheads are greatly populated in Scotland and Ireland. Pool, Ren Heritability estimates for hair color range from 61% to 100%, and for eye color similar high estimates are obtained (Brauer & Chopra, Reference Brauer and Chopra1980; Lin et al., Reference Lin, Mbarek, Willemsen, Dolan, Fedko and Abdellaoui2015; Zhu et al., Reference Zhu, Evans, Duffy, Montgomery, Medland and Gillespie2004). van t Hof, Peter The genetic mutation of a redhead means that both parents have to be carriers of the MC1R gene to produce a redhead offspring. van Duijn, Cornelia M.
