Is eye color determined by genetics?</h3>
- A person’s eye color results from pigmentation of a structure called the iris, which surrounds the tiny black hole which is located in the center of the eye (the pupil) and helps control the intensity of the light that enters the eye.
- The color range of the iris is from very light blue to dark brown. Brown is that the most frequent eye color worldwide.
- Eye color is decided by variations in a person’s genes.
- Most of the genes related to eye color are involved in the production, transport, or storage of a pigment called melanin.
- Eye color is directly associated with the amount of melanin in the front layers of the iris. People with brown eyes have an outsized amount of melanin in the iris, while people with blue eyes have much less of this pigment.
