Red hair and green eyes is a combination that’s thought about rare. The chances you or your kid will have actually it are based on whether your immediate family members had red hair or green eyes, though it have the right to skip generations.
You are watching: What is the rarest hair color and eye color combination
Having red hair or green eyes (or both) every comes under to her genes. Your genetic makeup is based on a mix of markers her parents have passed to you.
While having red hair and also green eyes isn’t common, it’s additionally not impossible, specifically if yes sir a history of the combination on both sides of her family.
Red hair and also green eyes with each other is a particularly rare occurrence. Both traits room the result of recessive genes, just as blue eye or O blood form is.
Being recessive or leading has nothing to do with even if it is or not a trait is common. Still, the mix of red hair and green eyes tends to be unusual in today’s population.
While the odds of having actually red hair and also green eyes depends on a selection of factors, it’s interesting to look in ~ the genes behind this combination. Each person’s DNA has 20,000 genes. Just a few of these genes dictate hair color and eye color.
The hair, skin, and also eye colors you born with room all controlled by her genes. Your parents passed this genes under to you, simply as their parents passed down their genetic makeup come them.
When it involves hair and also eye color, part genes are an ext dominant 보다 others. Yet leading doesn’t have to mean an ext common.
What determines your hair, eye, and skin color is a pigment referred to as melanin. Genes provide the indict for producing melanin. Your genes determine just how much that this pigment girlfriend have, and therefore, what shade hair and eyes girlfriend have.
The MCR1 gene dictates even if it is you have actually red hair, and it’s recessive. That way you’d must inherit copies from both parents to have this shade combination.
Genes also have variants, well-known as alleles. At least three different genes manage eye color, and there deserve to be more than 2 alleles because that each gene.
For example, the MCR1 gene come in two variants: non-red and also red. The non-red version is dominant. Gey, which is just one of the genes that determines eye color, come in 2 forms: Green and blue. Blue is the dominant allele.
But that doesn’t phone call the totality story.
Also an essential to how common a color combination is within a given population is i m sorry alleles are circulating. Because that example, alleles the the gene OCA2 identify whether someone has actually brown or not-brown eyes.
In populaces where an ext people have the not-brown OCA2 allele — prefer in Scandinavia — the allele for light eyes is much more common, even though it’s recessive. Light-eyed world pass their genes to their children, that pass lock to their children, and also that eye color perpetuates.

Red hair and green eye genes are simply not as common in populations as other hair and also eye colors.
One study found that the red hair-green eye genetic mix is among the rarest, in ~ -0.14 correlation. Having actually red hair and also blue eyes is even rarer.
