Inbreeding avoidance hypothesis

WebWe used 21 microsatellite markers to test for multiple paternities among 88 litters of roe deer, Capreolus capreolus, and to investigate the inbreeding avoidance hypothesis as a potential mechanism for the evolution of female multiple mating. From paternity analyses, we found that 13.5% of polytocous litters were sired by more than one male.

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.

WebAug 31, 1999 · Two genetic benefit hypotheses can be readily eliminated: (i) the sexually selected sperm hypothesis , because it predicts an advantage to polyandry that is not manifested until male offspring attain sexual maturity, and (ii) the inbreeding avoidance hypothesis (26, 27), because all experimental pseudoscorpions were first-generation, …
