... The strictest adherence to previously accepted N. crassa naming convention would be that genes not receive a symbol and name (e.g., cot-1 and colonial temperature sensitive-1) until a mutant phenotype is described or a function is demonstrated. However, it is not realistic to expect, for example, th ...

Epistasis
Epistasis is a phenomenon that consists of the effect of one gene being dependent on the presence of one or more 'modifier genes' (genetic background). Similarly, epistatic mutations have different effects in combination than individually. It was originally a concept from genetics but is now used in biochemistry, population genetics, computational biology and evolutionary biology. It arises due to interactions, either between genes, or within them leading to non-additive effects. Epistasis has a large influence on the shape of evolutionary landscapes which leads to profound consequences for evolution and evolvability of traits.
