Epistasis: History & Applications

Epistasis is a phenomenon in genetics in which the effect of a mutation on a trait is dependent on the presence or absence of mutations at different loci (locations on the genome), that may be on the same gene (intragenic) or on different genes, called modifier genes. In evolutionary genetics, epistasis occurs when the combined effect of two mutations is…
