I have hazel eyes, but my father has green eyes while my mother has brown eyes. How is this possible?

Hazel eyes are often described as a mixture of brown, green, and gold, with variations in how the colors appear under different lighting conditions. Hazel eye color is the result of multiple genes interacting to produce intermediate levels of melanin in the iris. Hazel eyes result from moderate amounts of melanin, which creates a mixture of colors. The brown pigment dominates in some parts of the iris, while green and lighter shades (due to lower melanin) show through in other areas.


Most human traits, such as height, skin color, eye color and intelligence, are influenced by many genes working together. This is called polygenic inheritance, where each gene contributes a small effect.


The polygenic nature of eye color means that a child’s eye color can be influenced by the genes inherited from both parents, leading to combinations that might not fit the simple brown-dominant, blue-recessive model that most of us were taught in high school biology.
