What are the genetics of light eye color? Lighter eye colors, such as blue and green, are found almost exclusively among people of European ancestry. Eye color is determined by variations in a person’s genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin.
Is light eye color dominant or recessive? For considering a trait as dominant or recessive, we need data of at least three generations. This data is about only two generations. However, since both children and their parents have light eye colour, the possibility is that light eye colour is a recessive trait.
Which parent determines eye color? Whether eyes are blue or brown, eye color is determined by genetic traits handed down to children from their parents. A parent’s genetic makeup determines the amount of pigment, or melanin, in the iris of the his or her child’s eye. With high levels of brown melanin, the eyes look brown.
What is the rarest genetic eye color? Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.

Is eye color a genetic trait?
Eye color is determined by variations in a person’s genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
What causes eye color to change from brown to green?

When did they start making different eye color contacts?
