Summary of Mendel’s Principles • 1. traits are determined by genes from parents to offspring. • 2. when present a dominant trait will always show up. 2 recessive traits must exist together for recessive to show up. • 3. each adult has two copies of a gene (one from each parent). These genes segrega ...

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.
