Question

Which is an environmental factor that affects skin color in humans?

amount of sunlight absorbed
amount of food consumed
number of genes inherited
number of linked genes

Answer 1

Amount of sunlight. The food consumed does not directly affect skin colour unless you’re considering eating too much carrots. Numbers of genes are genetic factors, not environmental factors

Answer 2

amount of sunlight absorbed

Step-by-step explanation:

Sunlight is from the environment and when we are exposed to sun, our skin is darker. The more sun we are exposed to, the darker our skin is, hence tanning.

Genes are not an environmental factor.

Food does not affect our skin colour.
