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.
Polygenic inheritance contributes to human skin color by... ...increasing the number of genes (there can be as many as 4). When this happens, the phenotypic variation increases. The alleles in this control the pigment that controls the skin color, which is called melanin. (A or B = 1 unit; a or b = 0 units).
