What gene is involved in eye color?
Genes play a big role in eye colors, which are more often seen in people with darker skin.
Researchers have found that a gene called melanosome 2 is a big driver of eye color variation, with researchers calling it a “central driver of the phenotypic differences in the iris, the outer skin covering the eye and the irises themselves.”
The gene has also been found to influence the structure of iris pigment cells, the inner layers of cells that make up the eye’s outer layer.
Eye color is a complex trait, with individuals with darker pigmentation typically have a broader range of irises and eyes, but with those with lighter pigmentation, more narrow irises.
This can be caused by genetic or environmental factors.
It can also be influenced by eye makeup.
The melanosomes are specialized for producing melanin, the pigment in the inner layer of skin, which makes up the outer layers of our eyes.
People with darker irises have darker melanosomal proteins in their skin, and these produce darker pigments in their irises as well.
This makes it easier for them to see in bright light.
The same holds true for eyes with more narrow pupils, like those with blue eyes.
The genes for eye color are a big part of what makes people different in the eyes of other species, so it’s no surprise that it’s important to understand how these genes work to see who has it.
