frequency-dependent selection any SELECTION in which the FITNESS of genotypes is directly related to the proportions of the various PHENOTYPES present in a population, so that the frequency of the more common types is decreased and the less common types is increased. Such selection pressure often produces a stable GENETIC POLYMORPHISM and when it involves predation is referred to as APOSTATIC SELECTION.

Specific aims of the proposed research is (1) to assess the effects of mito-nuclear genotype on key life history traits such as metabolic rate and test whether these effects are sex-specific in line with the mothers curse and (2) to test the hypothesis that mito-nuclear interactions promotes the maintenance of polymorphism in mitochondrial genome through negative frequency dependent selection
