Question

Quizplus · Accepted Answer

The most important factor in skin color is genetic factors. Different variations of genes control the amount and type of melanin produced by melanocytes, which determines skin color. Sunlight exposure, dermal blood supply, diet, and number of keratinocytes can all have some impact on skin color, but they are not as influential as genetic factors.
