Question

Quizplus · Accepted Answer

Polygenetic effects are produced by the interaction of many genes, meaning that multiple genes contribute to the expression of a trait. This is different from traits that are determined by a single gene (e.g. dominant or recessive). Random genetic mutation may contribute to variation in genes, but it is not the mechanism for producing polygenetic effects.
