Quizplus · Accepted Answer

Heredity, or the passing down of genetic information from parents to offspring, is the main reason for variation among humans. It is responsible for differences in physical traits such as eye color, height, and hair texture, as well as susceptibility to certain diseases. Environmental factors and lifestyle choices can also influence variation among humans, but these are typically secondary to the effects of heredity.
