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.
From a basic science perspective, variation in human skin color represents an unparalleled opportunity for cell biologists, geneticists, and anthropologists to learn more about the biogenesis and movement of subcellular organelles, to better characterize the relationship between genotypic and phenotypic diversity, to further investigate human origins, and to understand how recent human evolution may have been shaped by natural selection.
