Web14 sep. 2024 · Inheritance of Skin Color Skin color is largely determined by the amount of melanin. Dark-skinned individuals produce more melanin than light-skinned individuals. At least three genes regulate the amount of melanin produced. Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Melanin is produced by cells called melanocytes in a process called melanogenesis. Melanin is made within small membrane–bound packages called melanosomes. As they become full of melanin, they move into the slender arms of melanocytes, from where they are transferred to the keratinocytes. Under normal conditions, melanosomes cover the upper part of the keratinocytes and protect them from genetic damage. One melanocyte supplies melanin to thirty-six keratinoc… WebEye color is determined by variations in a person’s genes.
