Quizplus · Accepted Answer

Epistasis is a situation in which one gene masks the expression of another gene. This means that the presence of one gene affects the expression of another gene, either by suppressing or enhancing its expression. This can result in a phenotype that is different from what would be expected based on the individual's genotype.
