Red hair and also green eyes is a mix that’s thought about rare. The chances you or your son will have it are based upon whether your immediate household members had actually red hair or environment-friendly eyes, though it deserve to skip generations.
You are watching: What is the rarest hair color and eye combination
Having red hair or green eyes (or both) every comes under to your genes. Your genetic makeup is based upon a mix of markers her parents have actually passed to you.
While having red hair and green eyes isn’t common, it’s also not impossible, especially if there’s a history of the combination on both political parties of her family.
Red hair and green eyes together is a particularly rare occurrence. Both traits space the an outcome of recessive genes, just as blue eyes or O blood type is.
Being recessive or leading has nothing to execute with even if it is or no a characteristics is common. Still, the combination of red hair and also green eyes often tends to be uncommon in today’s population.
While the odds of having red hair and also green eyes counts on a selection of factors, it’s exciting to look in ~ the genes behind this combination. Every person’s DNA has 20,000 genes. Just a few of these gene dictate hair color and eye color.
The hair, skin, and also eye colors you born with room all controlled by her genes. Her parents passed this genes under to you, simply as your parents passed under their hereditary makeup come them.
When it pertains to hair and also eye color, some genes are much more dominant 보다 others. Yet leading doesn’t have to mean much more common.
What determines her hair, eye, and also skin color is a pigment dubbed melanin. Genes administer the indict for creating melanin. Your gene determine just how much that this pigment you have, and therefore, what color hair and eyes friend have.
The MCR1 gene dictates even if it is you have red hair, and it’s recessive. That way you’d should inherit duplicates from both parental to have actually this shade combination.
Genes also have variants, well-known as alleles. At the very least three different genes regulate eye color, and also there can be much 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 one of the gene that determines eye color, comes in two forms: Green and also blue. Blue is the leading allele.
But the doesn’t tell the whole story.
Also critical to how usual a color mix is within a given populace is i m sorry alleles room circulating. Because that example, alleles the the gene OCA2 determine whether someone has brown or not-brown eyes.
In populaces where an ext people have the not-brown OCA2 allele — choose in Scandinavia — the allele for light eyes is an ext common, even though it’s recessive. Light-eyed world pass their genes to their children, who pass lock to your children, and also that eye color perpetuates.

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