Human skin color varies widely around the world, and children do not always exhibit the exact same coloring as their parents. based on this information, what is true about human skin color?

a. skin color is not a genetic trait.
b. a single pair of alleles controls this trait.
c. it’s an example of incomplete dominance.
d. it’s an example of polygenic inheritance.

D.It’s an example of polygenic inheritance.

Explanation:

Polygenic inheritance occurs when more than one gene regulate single genetic trait. Human skin color is regulated by more than one gene and follows quantitative inheritance wherein total number of dominant alleles of all genes determine the skin color. Formation of various gene combinations by multiple genes regulating the skin color results in world wide variation of the trait as well as variations of skin color between parent and progeny.
