Skin Color is a Polygenetic (Multiple Gene) Trait

Differences in skin color are largely due to differences in the amount of melanin, a dark pigment, produced by skin cells. At least three genes control the synthesis of melanin. Each gene has two forms: an allele for high melanin production or dark skin (A,B,C) and an allele for low melanin production or light skin (a,b,c). Each dark skin allele (A,B,C) in the genotype adds a small but equal amount of pigment to the skin. There are seven different shades of skin color ranging from very dark (AABBCC) to very light (aabbcc). Most individuals produce a medium amount of melanin and are of intermediate skin color (AaBbCc). The more dominant alleles, the darker the skin color. See more at http://genetics.thetech.org/original_news/news27
