Only a few of these genes dictate hair color and eye color. photo source: Wallpaper Flare. Data Formats. Lin BD, et al. DOI: Sulem P, et al. For one to have red hair and blue eyes, the parents have to give them the MC1R recessive gene for red hair and the one for blue eyes. Jhamai, Mila How common is it for someone to have red hair and blue eyes? Hair coloring reached over 29 billion U.S. dollars in 2019 globally. Blondes have approximately 140,000 hairs compared with 108,000 for their darker counterparts. Just a few of these genes dictate hair color and eye color. And you somehow ended up with flaming red hair. 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. Both traits are the result of recessive genes, just as blue eyes or O blood type is. Learn about its uses, safety, and potential downsides here. Peripheral pigmentation traits such as eye, hair, and skin color show a close correspondence with latitudes in national to worldwide geographic regions: lower-pigmentation prevalence is found to be higher in high latitudes (Abdellaoui et al., Reference Abdellaoui, Hottenga, de Knijff, Nivard, Xiao and Scheet2013; Beleza et al., Reference Beleza, Santos, McEvoy, Alves, Martinho and Cameron2013). 42. vanDongen, Jenny Purely categorical data can be. It depends on whether genes are turned on or turned off. 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. Boomsma, Dorret I. Our website services, content, and products are for informational purposes only. Jansen, Rick 5. Schalkwijk, Casper G. Bartels, M. In most cases, youd have blue eyes and hair somewhere on the spectrum of blond to brown, or red hair with brown, hazel or green eyes. Kovacs, Michael A. for this article. The combination of red hair and blue eyes is the rarest color combination of all for human beings. The other six variants can lead to a range of blond to brown hair color.. Boomsma, Dorret I. Red hair is the result of a genetic variant that causes the bodys skin cells and hair cells to produce more of one particular type of melanin and less of another. 16. This is a very common combination as it also lies within the brown hair, brown eyes combination. Almost everyone (even people with blue or green eyes) has brown pigment in the back layer of the iris. 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. It's estimated that only one to two percent of the world population between 70 and 140 million people has red hair. Choi, Jiyeon Mei, Hailiang Verkerk, Marijn Many claim its a compensation to the fact that they have. DOI: Frost P, et al. 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. Plus, they may require more anesthetic during surgery or local anesthesia. Deelen, Patrick This in total leaves an estimate of 65 to 75% of the worlds population with brown hair and brown eyes. And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings. Anesthetic requirement is increased in redheads. Jan Bonder, Marc Verbiest, Michael Mei, Hailiang We avoid using tertiary references. The non-red version is dominant. In Africa, 1.2 billion people have black hair color. Studies have shown that nonfunctional MC1R, as seen in redheads, yields a higher tolerance to electrical stimulation and increased sensitivity to cold and heat.. The results confirmed the involvement of two genes, HERC2 and SLC24A4, in both hair color and eye color. Hottenga, J.-J. Heijmans, Bastiaan T. Willemsen, Gonneke The genetic overlap between hair and eye color. Hence, dark brown eyes add a sense of subtle to the mix. Still, some research has suggested that red hair is more common in women than in men. DOI: Martinez-Cadenas C, et al. Blonde hair can range from practically white (platinum blonde) to a dark golden blonde. Like red hair, left-handedness is a recessive trait. The amount and type of melanin your body produces determines how dark or light your skin will be. Genome-wide study of hair color in UK Biobank explains most of the SNP heritability. Recessive genes that dictate lighter eye color are most common in Scandinavia. 11. Just as the MC1R gene determines your hair color, a single gene, OCA2, is 75% responsible for your eye color, Dr. Kaplan says. Still, not everyone from Ireland or everyone with an Irish bloodline will end up having red locks. The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the melanin pathway. Dark green eyes like emerald appear close to brown eyes which eliminates the uniqueness of this combination. Even though natural black hair is the most common color, it is rare in combination with green eyes. 44. Precisely, individuals with red hair are the least common with less than two percent of the global population. 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. 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. That means 0.17 percent of the world's population, or roughly 13 million people, have this hair and eye color . Your hair color and eye color come down to what genes you inherit from your parents. Qiao, Shuo-Wang That makes the blue eye and red hair combination even more unlikely to happen. DOI: How does someone get red hair and blue eyes, ncbi.nlm.nih.gov/pmc/articles/PMC2740987/, pursuit.unimelb.edu.au/articles/are-redheads-with-blue-eyes-really-going-extinct, ncbi.nlm.nih.gov/pmc/articles/PMC1692342/, Why Its Easier to Trust Someone with Brown Eyes, What Are Freckles, Why Do They Appear, and More, Debra Sullivan, Ph.D., MSN, R.N., CNE, COI. This statistic is a powerful reminder of the uniqueness of the red hair and blue eyes combination. Wijmenga, Cisca :202201062021202097.1%4,537 . Most Common in: Mediterranean countries, Ireland, Scotland, Germany. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. and Wu, Haoyu Most Common Hair and Eye Color Combinations For the remaining over 90% of the population lies under black or brown hair, with others lying in between as brunettes. Knowing which genes play a role in hair and eye color variation can help us understand why some hues are more common than others. The iris has two layers. 10. Blue is the dominant allele. Redheads are thought to be more sensitive to pain, too, research shows. 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. Hair colors are a spectrum of hues ranging from white blond to coal black. That means that in total, 59.7% of men said they. 2022. For example, red/ pink eyes for albinism cant really be matched with blonde hair. Blue eyes contain much less melanin than brown eyes. Deelen, Patrick (2017). Keep in mind that children with the same parents can have different eye and hair colors. This indicates that the genetic PCs of the Dutch population are capturing the overlapping genetic variance of eye and hair colors. van Duijn, Cornelia M. Ward-Caviness, Cavin K Gudievskaya, Irena G. Black Hair is the most common hair color in the world, with an estimate of 75%-85% of the population having this shade. Franke, Lude The most common hair and eye combination for such is brown hair with brown eyes. The phenotypic association of eye and hair colors confirms the two traits to be strongly related in our sample ( This is true. It can cause infertility and other symptoms.

This medical condition, and perhaps others, seems facilitated by the combination of being red-haired and female. Unlike the usual dark brown, black, brunette, and blonde hair hues we see out there, theres a group of people who are natural redheads. This is a classic combination for all those light to dark brown-haired people. Verbiest, Michael For the genetic association analysis of eye color (see Supplementary material) all data were analyzed. DOI: Roider EM, et al. Whether you have one or both MC1R gene copies inactivated can also determine the shade of red hair you have, from strawberry blonde to deep auburn to bright red. Heijmans, Bastiaan T. Skrypnik, Olga V. Zhernakova, Alexandra Your genes determine how much of this pigment you have, and therefore, what color hair and eyes you have. 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. Slagboom, P. Eline (Cambridge University), Black hair with blue eyes is rarer than blonde hair and blue eyes combination (The Tech Interactive), Brown hair with brown eyes is the most common hair and eye color combination worldwide. How to Clean Every Room in Your Home: Smart Tips That Make Housecleaning Easier, Fasterand Done! This gene is responsible for their hair but also their skin color as it determines their skin pigmentation. Rarity: Quite Rare. Tigchelaar, Ettje F. van Dongen, Jenny count from dplyr produces aggregated data from raw data. Eye color results from the amount of pigment (melanin) you have in the front layer (stroma). The genetic mutation of a redhead means that both parents have to be carriers of the MC1R gene to produce a redhead offspring. 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 ). Veldink, Jan H. At least three different genes control eye color, and there can be more than two alleles for each gene. van den Berg, Leonard H. Brown to also mean brunettes. Parents share the blueprint of many features, from hair color to personality, in their genes. It sends signals to the melanocytescells that create melanin in your bodyand depending on your genes, it creates eumelanin (usually associated with darker hair and skin) or pheomelanin (associated with light-colored hair, like red or blond, and fairer skin). Dekkers, Koen F. Kallsen, Noah A. 34. Li, Ding 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. Only 2% of people in the world are natural blondes. van Meurs, Joyce B. J. Kumar, Vinod One study found that the red hair-green eyes genetic combination is one of the rarest, at -0.14 correlation. (Cambridge University) Even so, various factors come into play when discussing commonalities. Healthline Media does not provide medical advice, diagnosis, or treatment. t Hoen, Peter-Bram (Readers Digest), Between 55% and 79% of the worlds population has brown eyes. and Last medically reviewed on September 18, 2018. See, we like to think theres a rainbow of eye color options out thereviolet, blue, gray, hazel, green, brown, near-blackbut scientists believe that theyre all slightly different manifestations of blue eyes or brown eyes. Two nonfunctional copies of OCA2 yield blue eyes, says Dr. Kaplan. The genetic correlations between the hair and eye colors are presented in Table 3. Bell, Jordana T. 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. DOI: Liem EB, et al. 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. and The true pattern of inheritance of hair color is somewhat more complicated, though, as there are many genes involved. Subscribe Prev Article Next Article Blue is the dominant allele. van Zwet, Erik. However, the natural blend is harder to acquire since the number of true blondes is slightly under 10% of the global population. Our DNA has 20,000 genes. Red hair is most commonly associated with Ireland. Nooren, Irene What determines your hair, eye, and skin color is a pigment called melanin. Finally, there is a clear and strong genetic overlap for brown eyes and a dark hair color. Brown is the most common eye color in the United States, just as it is globally. 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. The majority of redheads have brown, hazel, or green eyes. Other studies indicate more rare combinations such as amber eyes and blonde white hair. Genes also have variants, known as alleles. Claringbould, Annique Kielbasa, P. Szymon M. I'm Athena, your personal Hair Stylist. The likelihood of this happening is quite rare, especially if neither of your parents has red hair or blue eyes. This is because they naturally have lower melanin concentration. The action you just performed triggered the security solution. Both parents can display recessive gene characteristics, and they can pass those to their children, too. DNA Methylation: Can Your Diet Reduce Your Risk of Disease? Santoni, Federico A.

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. 200 . Next up is red hair and green eyes. Norway, Sweden, Denmark, Iceland, and Finland have the highest blonde hair rates. 48. 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. Red hair, light skin, and UV-independent risk for melanoma development in humans. What are the rarest hair and eye color combinations?
