Which of the following is a form of polygenic inheritance in which the effect of an allele on a trait masks the effect of a different gene?  
A) Pleiotropic
B) Epistasis
C) Codominance
D) Incomplete dominance
E) Continuous variation

Quizplus · Accepted Answer

Epistasis is when the effect of one gene on a trait masks the effect of a different gene. This is a form of polygenic inheritance, where multiple genes contribute to the expression of a trait. Pleiotropy refers to when one gene affects multiple traits, while codominance and incomplete dominance refer to how alleles interact to produce traits. Continuous variation refers to when a trait varies along a spectrum rather than being discrete, and is not necessarily related to polygenic inheritance.
