Web1. , 2. ]. Animal ecologists commonly assume that inbreeding depression will drive the evolution of reproductive strategies that result in inbreeding avoidance, including sex-biased dispersal, specific choice of unrelated mates, and associated mechanisms of kin recognition and sperm selection [. 3. , 4. WebFor species with the type of dispersal shown in Fig. 1, we seem to be left with two modified versions of the inbreeding avoidance hypothesis: (1) individual selection has produced a remarkably inefficient, pessimal mechanism; or (2) differential dispersal as a mechanism of reducing inbreeding evolved by interdemic selection. …
