Inbreeding avoidance hypothesis
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.

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 ).
