Red hair and also green eyes is a mix that’s considered rare. The possibilities you or your boy will have actually it are based on whether her immediate family members had red hair or environment-friendly eyes, despite it can skip generations.

Having red hair or eco-friendly eyes (or both) all comes down to her genes. Your hereditary makeup is based upon a mix of markers her parents have passed to you.
While having red hair and green eye isn’t common, it’s additionally not impossible, particularly if there’s a history of the combination on both sides of your family.
Red hair and green eyes together is a particularly rare occurrence. Both traits are the an outcome of recessive genes, just as blue eyes or O blood form 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 actually red hair and also green eyes counts on a range of factors, it’s amazing to look at the genes behind this combination. Every person’s DNA contains 20,000 genes. Just a couple of of these gene dictate hair color and eye color.
The hair, skin, and eye colors you born with are all controlled by your genes. Her parents passed this genes under to you, simply as your parents passed down their genetic makeup to them.
When it pertains to hair and also eye color, part genes are much more dominant than others. Yet leading doesn’t necessarily mean much more common.
What determines her hair, eye, and skin shade is a pigment dubbed melanin. Genes administer the instructions for producing melanin. Your gene determine just how much the this pigment girlfriend have, and therefore, what color hair and also eyes girlfriend have.
The MCR1 gene dictates even if it is you have actually red hair, and also it’s recessive. That method you’d have to inherit copies from both parents to have this color combination.
Genes likewise have variants, known as alleles. At the very least three different genes regulate eye color, and also there can be much more than two alleles because that each gene.
For example, the MCR1 gene comes in two variants: non-red and also red. The non-red variation is dominant. Gey, which is just one of the gene that identify eye color, come in 2 forms: Green and also blue. Blue is the dominant allele.
But that doesn’t phone call the totality story.
Also vital to how common a color combination is in ~ a given populace is i beg your pardon alleles are circulating. For example, alleles of the gene OCA2 determine whether someone has actually brown or not-brown eyes.
In populations where more people have actually the not-brown OCA2 allele — prefer in Scandinavia — the allele because that light eye is more common, also though it’s recessive. Light-eyed human being pass their gene to your children, that pass lock to your children, and that eye color perpetuates.

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