D)​genetic drift

Quizplus · Accepted Answer

When two or more genes contribute to the phenotypic expression of a single characteristic, it is known as polygenetic inheritance. Punctuated equilibrium refers to a pattern of evolution, clinal expression is not a recognized term in genetics or biology, and genetic drift refers to random changes in gene frequencies in a population.
