Answer:

the skin color

Explanation:

One of the variations that take place is the skin color of people. The skin color is usually affected by factors such as the environment that a person lives in. In fact, in biology, the phenotype of a person is both a work of the genotype and environmental factors. One of the environmental factors to the skin color might be the melanin amount in the skin.
