Eye Color Science: Genetics, Melanin, and Unique Traits
Your eye color is a mix of science and genetics.
It's all about a pigment called melanin, which absorbs light.
Brown eyes have a lot of melanin, while blue eyes have very little.
Green eyes are a mix of melanin and how light scatters.
Many genes play a role, so even blue-eyed parents can have children with different eye colors.
Your eye color can change slightly due to light or even clothing.
Eye color also reveals ancestry and heritage.
Eye color is influenced by melanin, light scattering, and genetics.
Melanin levels determine eye color, with brown eyes having high melanin.
Blue eyes have little melanin; their color comes from light scattering.
Multiple genes interact to determine eye color.
Eye color can be affected by light, clothing, or medical conditions.
