The definition of epistasis is when the allele of one gene interferes with or modifies the expression of another gene. This interference can result in the masking or altering of phenotypic traits. Epistasis can occur in various forms, such as dominant epistasis, recessive epistasis, duplicate recessive epistasis, and duplicate dominant epistasis.
