AP BIOLOGY

Detailed explanation-1: -Eye colour, skin tone and face shape are all determined by our genes so any variation that occurs will be due to the genes inherited? from our parents. In contrast, although weight is partly influenced by our genetics?, it is strongly influenced by our environment.

Detailed explanation-2: -Abstract. Differences in skin and hair color are principally genetically determined and are due to variation in the amount, type, and packaging of melanin polymers produced by melanocytes secreted into keratinocytes.

Detailed explanation-3: -People from tropical regions of the world at or near the equator generally have darker skin than people who live in temperate regions farther from the equator, because variation in human skin color is closely related to geographic variation in solar radiation.

Detailed explanation-4: -Genetic variation-these are differences between individuals that are inherited from parents, such as the colour of your eyes, hair and skin.
