Question

1. human skin color is controlled by many pairs of genes, this inheritance pattern is called: a. epistasis b. multiple alleles c. polygenic inheritance d. pleiotropy e. none of these are correct

Explanation:

Epistasis involves one gene masking the effect of another. Multiple - alleles refer to more than two alternative forms of a gene at a single locus. Pleiotropy is when a single gene has multiple phenotypic effects. Polygenic inheritance is the inheritance pattern where a trait is controlled by multiple pairs of genes, which is the case for human skin color.

Answer:

C. polygenic inheritance
