Inbreeding avoidance hypothesis
WebApr 11, 2024 · According to the inclusive fitness theory, one of the leading hypotheses is that people are more likely to behave altruistically toward near relations, with the degree of relatedness dictating the level of altruism. Numerous investigations on various animals, from insects to primates, have confirmed this hypothesis. WebApr 13, 2015 · The ‘inbreeding avoidance’ hypothesis posits that males disperse to avoid inbreeding with related females, resulting in density-independent sex-biased dispersal [ 14 ].

WebMar 12, 2014 · Inbreeding avoidance may also increase the genetic diversity of progeny, which might confer fitness benefits in temporally and spatially heterogeneous environments. Yet, several recent studies have surprisingly reported evidence for mate choice for genetically related reproductive partners [ 11 – 13 ]. WebUnder the inbreeding avoidance hypothesis, EPO should not suffer the inbreeding depression that results from the expression of recessive deleterious alleles or perhaps from loci where heterozygous combinations are advantageous (Charlesworth and Charlesworth 1987; Hedrick and Garcia‐Dorado 2016 ).

We observed little difference in reproductive success between females mated to two siblings or females mated to two nonsiblings.
