how mutations affect gene function
... Missense mutation: changes an amino acid to another amino acid. This may or may not affect protein function, depending on whether the change is “conservative” or “nonconservative,” and what the amino acid actually does. Nonsense mutation: changes an amino acid to a STOP codon, resulting in prematur ...

Male Driven Evolution
... The zinc-finger protein-coding genes are a good case for studying the ratio of male to female mutation rates because in all mammals there are two homologous genes, an X-linked one (Zfx) and an Y-linked gene (Zfy). Shimmin et al. (1993) sequenced the last intron of Zfx and Zfy genes in human, orangu ...

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.
