Baldwinian Accounts of Language Evolution

Heterozygote Advantage: The Effect of Artificial Selection in

There are a number of mutants in livestock and pets that have a heterozygote advantage because of artificial selection for these mutants in heterozygotes and strong detrimental effects from natural selection in homozygotes. In livestock, these mutants include ones that influence milk yield in dairy ...

Developmental buffering: how many genes?
... Although most studies of Hsp90 and phenotypic variability have been conducted in Drosophila, similar patterns appear also to hold for other organisms. In zebrafish, pharmacological inhibition and knockdown of Hsp90 induced a range of specific abnormalities depending on the genotype (Yeyati et al. 2007 ...

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.
