For example, EPMs enable females to copulate with unrelated males and reduce the risks of inbreeding (inbreeding avoidance hypothesis; Foerster et al., 2003, Forstmeier et al., 2011, Pusey and Wolf, 1996, Wells et al., 2024 ).

WebApr 13, 2015 · Male-biased dispersal, in contrast, is classically explained by the ‘inbreeding avoidance’, ‘mate competition’ or ‘resource competition’ hypotheses [ 9, 12, 13 ]. The ‘inbreeding avoidance’ hypothesis posits that males disperse to avoid inbreeding with related females, resulting in density-independent sex-biased dispersal [ 14 ]. WebApr 18, 2013 · Inbreeding depression (the accumulation of recessive deleterious alleles and loss of heterosis) is strongly positively correlated with degree of kinship of sexual partners ( Lynch and Walsh 1998 ), and the negative consequences of inbreeding for fitness are well documented across species ( Keller and Waller 2002 ), including humans ( Postma et … alessi sibi

WebThe inbreeding avoidance hypothesis predicts that females paired with closely related males should seek copulations with distantly related extra-pair partners to avoid fitness … WebIn addition to the assumptions that EPO should have a reduced degree of inbreeding and that there is inbreeding depression in the population, the inbreeding avoidance hypothesis also predicts that more closely related pairs should have higher EPP rates (Leclaire et al. 2013; Arct et al. 2015 ). WebSeveral theoretical hypotheses have been proposed to explain the evolution of this bias: the resource competition hypothesis proposed by Greenwood, the local mate competition hypothesis, and the inbreeding avoidance hypothesis. Those hypotheses argued that the mating system should be the major factor explaining the direction of such bias. alessi stainless carafe
