Is it true that the color of the eye is determined by genes?

The color of the iris (the colored part of the eye) is determined by the amount and type of pigment in the iris. The genes that control the production and distribution of this pigment can affect the color of the iris. For example, the presence of the pigment melanin produces brown eyes, while a lower amount or absence of melanin produces blue or green eyes.

Eye color is generally determined by multiple genes that interact with each other, making it a complex trait. It is possible for parents with certain eye colors to have children with different eye colors depending on the combination of genes inherited by their offspring.
