Detailed explanation-1: -One such relationship is epistasis, which is the interaction of non-allelic genes where the effect of one gene is masked by another gene to result either in the suppression of the effect or they both combine to produce a new trait (character).

Detailed explanation-2: -The term “epistasis” is sometimes used to describe some form of statistical interaction between genetic factors and is alternatively sometimes used to describe instances in which the effect of a particular genetic variant is masked by a variant at another locus.

Detailed explanation-3: -Epistasis is the interaction between genes that influences a phenotype. Genes can either mask each other so that one is considered “dominant” or they can combine to produce a new trait. It is the conditional relationship between two genes that can determine a single phenotype of some traits.

Detailed explanation-4: -Epistasis is the non-allelic gene interaction where the presence of one gene masks or alters the expression of another gene thereby not allowing the later one to express fully. Coat color in mouse and fruit color in squash are the examples of epistasis.
