Inbreeding avoidance in animals
WebDec 1, 2014 · As breeding between relatives often results in inbreeding depression, inbreeding avoidance is widespread in the animal kingdom. However, inbreeding avoidance may entail fitness costs. For example, dispersal away from relatives may reduce survival. WebInbreeding and its avoidance are also likely to impact on the evolution of coopera-tive breeding itself through influencing levels of relatedness between potential cooperators. …

WebMay 11, 2024 · Given the mechanisms of inbreeding avoidance that animals appear to have at their disposal, it is perhaps surprising that inbreeding occurs at all. However, it is important to recognize that both inbreeding and inbreeding avoidance are likely to have costs, and how these balance against each other appears to result in substantial variation … Inbreeding avoidance, or the inbreeding avoidance hypothesis, is a concept in evolutionary biology that refers to the prevention of the deleterious effects of inbreeding. Animals only rarely exhibit inbreeding avoidance. The inbreeding avoidance hypothesis posits that certain mechanisms develop within a species, or within a given population of a species, as a result of assortative mating, natural and sexual selection in order to prevent breeding among related individuals in tha…
