Epistasis

Phenomenon in genetics that one gene (a pair of alleles) suppresses the operation of another gene (pair of alleles). Epistasis is a type of a non-Mendelian inheritance pattern. Epistasis comes in different types.

Note:

Epistasis may also occur between three or more genes, in quantitative genetics.
NT: dominant epistasis ↔ recessive epistasis ↔ cumulative isomerynon-cumulative isomery ↔ reciprocal dominant epistasis ↔ reciprocal recessive epistasis
