The Genetics of Eye Color

The inheritance of eye color is a complex trait influenced by multiple genes. The two primary genes involved are OCA2 and HERC2, which control the production and distribution of melanin in the iris. Melanin is the pigment responsible for the color of our eyes, hair, and skin.

Blue eyes occur when there is a low level of melanin in the iris, resulting in a light color. In contrast, gray eyes have even less melanin and are characterized by a unique scattering of light. Below is a simplified genetic breakdown of eye color inheritance:

• **Brown eyes**: Dominant trait.
• **Blue eyes**: Recessive trait.
• **Gray eyes**: Also considered a recessive trait, often resulting from a combination of low melanin and structural coloration.
