Sometimes one gene pair will interact so as to control the expression of a second gene pair in an interaction called
A)dominance.
B)gene regulation.
C)recessiveness.
D)pleiotropy.
E)epistasis.

Question

Quizplus · Accepted Answer

Epistasis is the gene interaction in which one gene pair affects the expression of a second gene pair. This is different from dominance and recessiveness, which refer to the relationship between alleles of a single gene, and pleiotropy, which refers to a single gene affecting multiple traits. Gene regulation is a general term for the mechanisms controlling gene expression, but it does not specifically refer to gene interactions. Therefore, epistasis is the best answer.
