Inbreeding is a form of non-random mating
Web(2) Inbreeding: mating between related individuals. – Both types of nonrandom mating may have similar consequences since individuals with similar phenotypes often have similar genotypes. – It is often difficult to separate cause from effect. • E.g., individuals with similar phenotypes may mate because a) phenotypic assortative mating occurs; WebNon-random mating won't make allele frequencies in the population change by itself, though it can alter genotype frequencies. This keeps the population from being in Hardy-Weinberg equilibrium, but it’s debatable whether it counts as evolution, since the allele frequencies …

WebMar 1, 2024 · Results from generalized linear mixed models suggest that the pattern of MHC‐dependent disassortative mating could be a by‐product of inbreeding avoidance, and suggest that while multiple apparent mechanisms of non‐random mating with respect to the MHC may occur, some of them have alternative explanations.

WebWhen nonrandom mating occurs because there is a specified system of partial inbreeding every generation, alpha can be substituted by Wright's FIS statistic, to give the effective size as a function of the proportion of inbred mates. MeSH terms Breeding Gene Frequency
WebInbreeding and outbreeding are evolutionary strategies adopted by plants and animals living under certain conditions. Outbreeding brings gametes of different genotypes together, and the resulting individual differs from the parents. Increased levels of variation provide more evolutionary flexibility. chrome password インポートWebTherefore, non-random mating can have some indirect consequences for evolution.
