Epistasis

Epistasis (pronounced: /ɪˈpɪstəsɪs/) is a phenomenon in genetics where the effect of one gene is dependent on the presence of one or more 'modifier genes', i.e., the genetic background.

Etymology

The term 'epistasis' is derived from the Greek word 'epistasis', meaning 'stopping' or 'standing upon'. It was first used in the context of genetics by the British geneticist William Bateson in 1907.

Definition

In the field of genetics, epistasis refers to the interaction between different genes, where the expression of one gene is influenced by the presence or absence of another gene. This interaction can either mask the effects of one gene (recessive epistasis) or enhance the effects of one gene (dominant epistasis).
