Rating Newest Oldest. Best Answer: Polygenic Inheritance: Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three dominant capital letter genes (A, B and C) control dark pigmentation because more melanin is produced.
Researchers Identify Human Skin Color Gene. Ten years ago researchers embarked on a study of zebrafish--a quick breeding aquarium pet. While searching for cancer causing genes, they ended up isolating the gene that makes European skin white, thanks to the golden variant of the fish. The genetic basis for human skin color has eluded scientists for years, with previous studies pointing to more than 100 different genes involved in the production of melanin--the pigment responsible for skin color and a natural sunblock.
