DOI: Mengel-From J, et al. 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. Whats more fascinating is that there more to it than just the unique color of the hair, its the hair and eye combinations. Blue is the dominant allele. Cao, Yue 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. 21. Even so, there are still genetic complexities that make it hard to dictate these traits for your offspring. Keep reading to learn what the rarest hair and eye color combinations are, plus other tidbits of information, including facts about redheads. Genome-wide study of hair color in UK Biobank explains most of the SNP heritability. Our website services, content, and products are for informational purposes only. It may seem like green is rare, says Dr. Kaplan, but there are many people who have green-brown eyes.. Both hair and eye color are highly heritable. Brown to also mean brunettes. Wu, Maowang 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. Genes also have variants, known as alleles. 37. and When a person has a child, they can pass their recessive gene information to their offspring, and the trait could win out. van der Kallen, Carla J. H. van Greevenbroek, Marleen M. J. Millions of unique hair color shades people wear around the world. van Iterson, Maarten This makes it difficult to separate the effects of population stratification and the true genetic effects of variants on these particular phenotypes. Black hair is a very common trait for fair-skinned people. vanDijk, Freerk 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. Nivard, M. G. Note: aThis variable is Blond hair + blue eyes in the 1908 data and Blond hair + blue/gray eyes in the 2004 data. (World Atlas), Green eyes occur in only 2% of the global population. Teumer, Alexander 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). DOI: Grant MD, et al. 75-84% of the world's population has naturally black or dark-brown hair (depending on the study). 53. Jhamai, Mila But from 1936 to 1951, that number fell to 33.8 percent. Lakenberg, Nico What are the rarest hair and eye color combinations? 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. Plus, they may require more anesthetic during surgery or local anesthesia. Vermaat, Martijn In people with an activated MC1R, eumelanin can balance pheomelanin, but in redheads, the gene variant prevents that. 19. (World Atlas), Hazel and amber are rare eye colors, with around 5% of people around the world having this eye color, respectively. and Santoni, Federico A. They say beauty lies in the eye of the beholder, but in some cases, beauty thrives in whats unique. (World Atlas), Between 8% and 10% of people worldwide have blue eyes. Franke, Lude 1% of the worlds population has gray or white hair worldwide. Schalkwijk, Casper G. Why Is Red Hair And Blue Eyes The Rarest Combination? Performance & security by Cloudflare. Blondes are typically more outgoing and lively and are perceived as more feminine than women with other hair colors. 75% of American women dye their hair today. Stehouwer, Coen D. A. Parra, Esteban J. TABLE 3 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. and Luijk, Ren aggregated into counts for unique level combinations.

Schalkwijk, Casper G. Your parents passed these genes down to you, just as their parents passed down their genetic makeup to them. 46. Hair coloring reached over 29 billion U.S. dollars in 2019 globally. Liu, Qingfan Its pigmentation is deeper, harder, and tighter to remove or change than any other type of hair. 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. Even so, various factors come into play when discussing commonalities. 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). You can imagine a natural blonde like Drew Barrymore with amber eyes. View all Google Scholar citations W. Rimbert, Antoine Another fun fact about redheads? Your hair color and eye color come down to what genes you inherit from your parents. As for the combination of the red hair and blue eyes, little research has looked at which sex is more likely to develop this uncommon characteristic combo. van Meurs, Joyce 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). Sex and age were used as covariates in the analyses. Jhamai, P. Mila Today, estimates suggest about 17 percent of people worldwide have blue eyes. Skrypnik, Olga V. Sanna, Serena (2018). Statistically speaking, redheads are only two percent of the global population, while blue eyed individuals make up 17%, a stunning total of only 13 million people in the entire world. 34. As of 2019, over 64 million people used hair coloring products on their hair. Published online by Cambridge University Press: Ye, Ke 38. Davies, Gareth E. I'm Athena, your personal Hair Stylist. The number of people with brown hair is relatively small. Verweij, K. J. H. van den Berg, Leonard H. Brown hair and brown eyes, for example, are both dominant, which is why they make up such a large percentage of hair-eye color combinations. You can learn more about how we ensure our content is accurate and current by reading our. But what tops the list is red hair and blue eyes. Though hair color is influenced by multiple genes, in general, dominant genes win out in a head-to-head matchup against recessive genes. 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 can't absorb . Like red hair, left-handedness is a recessive trait. For example, the MCR1 gene comes in two variants: non-red and red. cross-tabulated. 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. Only a few of these genes dictate hair color and eye color. The resultant visible hue depends on various factors, but always has someyellowishcolor. van der Maarel, Silvere M. 31. In most cases, you'd have blue eyes and hair somewhere on the spectrum of blond to brown, or red hair with brown, hazel or green eyes. Mei, Hailiang Nooren, Irene Suchiman, H. Eka D. Each occurrence (hair color and eye color) is instead programmed in your DNA by the genes you carry from both your parents. A person's eye color reflects a unique combination and concentration of pigments in the iris. Zhang, Beilei Is hair color determined by genetics? Light-eyed people pass their genes to their children, who pass them to their children, and that eye color perpetuates. Both hair and eye color are highly heritable. van Rooij, Jeroen This is due to the nature of brown genes being a dominant gene. That is why the combination of amber eyes with brown hair is also rare. And its not just because of MC1R. Weihs, Antoine Melanocytes are melanin-forming cells in your skin. The likelihood of this happening is quite rare, especially if neither of your parents has red hair or blue eyes. Red hair, light skin, and UV-independent risk for melanoma development in humans. 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. Breeze, Charles E. Vsa, Urmo If the allelic association between the specific platform allele frequency and the other platform's allele frequency was significant (p < 105) SNPs were removed. Red hair and green eye genes are simply not as common in populations as other hair and eye colors. Stehouwer, Coen D. A. bThe province of Flevoland consists of reclaimed land and did not yet exist in 1908. Blue eyes are similarly uncommon, and they may be becoming rarer. van Zwet, Erik W. Other common hairs and eye combinations include; This is a blend that others claim is overrated. :202201062021202097.1%4,537 . Light hazel is the lightest form of brown eyes, just very bright when reflected on the sun. van Zwet, Erik. 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. Hence, women have a higher gene mutation for the melanocortin 1 receptor (MC1R). That means that in total, 59.7% of men said they. 16. Zhernakova, Sasha Its all thanks to a single gene. Franke, Lude Eye color results from the amount of pigment (melanin) you have in the front layer (stroma). Franke, Lude DOI: Martinez-Cadenas C, et al. 2023 Healthline Media LLC. Uitterlinden, Andr G. This left 3,619 individuals for the bivariate analyses, with a genetic relatedness equivalent to less than third or fourth cousin. Hence, dark brown eyes add a sense of subtle to the mix. Almost everyone (even people with blue or green eyes) has brown pigment in the back layer of the iris. It can cause infertility and other symptoms. Hottenga, Jouke J. Also critical to how common a color combination is within a given population is which alleles are circulating. Subsequently, three Dutch PCs were calculated in the remaining individuals to account for the population stratification of regions where people live in the Netherlands. Thats followed by blonde hair. At least three different genes control eye color, and there can be more than two alleles for each gene. (2016). Deng, Chuwei van Iterson, Maarten Red hair and green eye genes are simply not as common in populations as other hair and eye colors. Mei, Hailiang The MCR1 gene dictates whether you have red hair and is recessive. 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. Its also possible to get more information via genetic testing. The data came from unrelated individuals (N = 3,619) registered with the Netherlands Twin Register, which includes participants from all regions of the Netherlands. This left 5,987,253 SNPs, which were all used to construct a GRM. Claringbould, Annique Choi, Jiyeon Here, we focus on the question whether all genes affecting one of these visible traits also affect the other trait. vanDongen, Jenny Boomsma, Dorret I. Luijk, Ren We tested this hypothesis by questioning a large sample of Czech and Slovak respondents about the natural redness and darkness of their hair, their natural eye color, their physical and mental health (24 categories), and other . Black and brown hair: Up to 95% black or brown eumelanin and approximately 5% pheomelanin. Abdellaoui, A. 9. Hostname: page-component-789cc574b8-jngkm Carnero-Montoro, Elena Jansen, Rick Health status by gender, hair color, and eye color: Red-haired women are the most divergent. Jansen, Rick 2018. van Dongen, Jenny Blondes have approximately 140,000 hairs compared with 108,000 for their darker counterparts. Beekman, Marian Hottenga, Jouke J. and Today she specializes in the latest African American styles and trends, serving her local community. Learn about its uses, safety, and potential downsides here. Dekkers, Koen F. 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. DOI: Genetics behind red hair and green eyes together. Red hair with green/hazel eyes showed the weakest correlation (-0.14). van Zwet, Erik W. A pair of blue-eyed parents can still have a brown-eyed child, depending on how all the genes interact. Keep in mind that children with the same parents can have different eye and hair colors. DOI: Eiberg H, et al. 41. We've rounded up the best kits and details about each so you can. By the way, which one is itblond or blonde? 45. Blonde hair: About 33% pheomelanin and approximately 66% brown eumelanin (no black eumelanin). Porcu, Eleonora Survey of Ophthalmology , 41 (Suppl 2), S117-123 https://www.ncbi.nlm.nih . People with red hair are seen to be more attractive than other types of people with blonde, black, or brunette. Need some help with your hair color? Find out how hair coloring represents itself in the hair care industry and market. Even so, this is a combination thats not hard to find. (2002). 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. Daxinger, Lucia So whats the rarest eye color? This is a very common combination as it also lies within the brown hair, brown eyes combination. vanHeemst, Diana 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. Heijmans, Bastiaan T. Bonder, MarcJan Learn about its uses, safety, and potential downsides here. Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Sollid, Ludvig M. Boomsma, Dorret I. Kielbasa, P. Szymon M. Hair colors are passed down through generations. 24. Yes, dark red to ginger is very common in areas like Ireland and very uncommon in other continents like Africa. van Beijsterveldt, Catharina E. M. 2023 Healthline Media LLC. Mao, Zhengsheng Hofman, Bert A. 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.

Min, Josine L. Lin BD, et al. Freckles are a result of genetics and too much sun exposure. Gene therapy can treat certain genetic conditions by editing diseased cells. Subscribe Prev Article Next Article Most Common in: Mediterranean countries, Ireland, Scotland, Germany. This is due to the nature of brown genes being a dominant gene. From a health perspective, it doesnt matter where you live if you have red hair and green eyes. Theres HERC2, a gene that controls how the OCA2 gene works, essentially turning P protein production on and off. The iris is the colored part of the eye that surrounds the pupil. While they may display the dominant genes, they still have and can pass to their kids the recessive genes. Being recessive or dominant has nothing to do with whether or not a trait is common. Theres a little genetic tweak that makes the combination of red hair and blue eyes the rarest of them all. People go to the salon at about the same rate, perhaps due to the soothing draw of the professional hair care experience. van der Kallen, Carla J. H. 42. van Meurs, Joyce B. J. 2018. The most common hair and eye combination for such is brown hair with brown eyes. Both parents can display recessive gene characteristics, and they can pass those to their children, too.
