Question

Quizplus · Accepted Answer

Continuous variation is most likely the result of all of these factors. Pleiotropy is the phenomenon of a single gene affecting multiple traits. Incomplete dominance is the phenomenon of a heterozygote having a phenotype that is intermediate between the two homozygotes. Epistasis is the phenomenon of one gene affecting the expression of another gene. Environmental effects can also contribute to continuous variation.
