Detailed explanation-1: -Eye color is directly related to the amount of melanin in the front layers of the iris. People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment. A particular region on chromosome 15 plays a major role in eye color.

Detailed explanation-2: -Simply put: The higher the concentration of melanin pigment in the iris, the darker the eye color. And a higher concentration of pigmented cells within the iris acts as an internal sun-shade, dissipating more sunlight and radiation.

Detailed explanation-3: -Iris: The iris is the colored part of the eye that surrounds the pupil.

Detailed explanation-4: -Your eye color results from the amount of melanin your body makes. Melanin is a pigment that gives color to your eyes, hair and skin. Genes determine your eye color. The iris (the colored part of the eye) can range from light blue or gray to very dark brown, in a full spectrum of shades.

Detailed explanation-5: -Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom’s dominant trait.
