Linkage arrangement in the vitellogenin gene family of Xenopus
... Structural studies of the four vitellogenin genes have revealed some features which are consistent with the proposed model of their evolution, while some others contradict 1t. The strongest support comes from the linkage between the genes Al and Bl (7), and from the similar degree of divergence with ...

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.
