Then, we combined these probabilities following Sokal & Rohlf (1995, p. 794-797) to examine a general tendency. ... tain whether inbreeding avoidance based on kin recognition by genetic sim-ilarity occurs in the field. To demonstrate inbreeding avoidance by genetic Webdescendants, thereby intrinsically reducing future inbreeding risk (the indirect inbreeding avoidance hypothesis). However such effects have not been quantified in naturally complex mating systems that also encompass iteroparity, overlapping generations, sequential polyan-dry, and polygyny. We used long-term social and genetic pedigree data
WebThe inbreeding avoidance hypothesis predicts that females paired with closely related males should seek copulations with distantly related extra-pair partners to avoid fitness … WebApr 24, 2015 · Inbreeding avoidance is therefore an ESS for M1 (i.e., M1 should always avoid inbreeding), but the maximum payoff is only realised if M2 also avoids inbreeding.

WebInbreeding depression should select for inbreeding avoidance behaviours. Here we test this hypothesis in two populations of the simultaneous hermaphroditic freshwater snail Physa acuta. We recorded the copulatory behaviour of 288 pairs of sib-mates, non-kin mates from the same population, or non-kin mates from two different populations. WebPatterns of mate preference in Morocco are investigated in order to test whether they support hypotheses advanced by David Buss and other evolutionary psychologists. Because of the custom of cousin marriage in Morocco, a multivariate model that included cosocialization data was developed for the purpose of testing the Westermarck …
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.

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 ). readers \\u0026 writers problemWebSeveral 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.
