Question

Quizplus · Accepted Answer

Epistasis occurs when one gene pair interferes with the expression of a second gene pair. This can result in masking of the phenotype of the second gene pair or modification of its expression. In contrast, incomplete dominance and codominance involve the blending or sharing of traits between two or more alleles. Blending inheritance refers to the mixing of traits from both parents to create a new phenotype, which is not related to epistasis. Pleiotropy occurs when one gene affects multiple traits, which is also not related to epistasis.
