WebDec 10, 2007 · Inbreeding avoidance mechanisms are expected to evolve in high-density populations that have an elevated risk of inbreeding (Brooker et al. 1990). Studies on seminatural mouse populations have provided evidence for the existence of small, semi-isolated breeding groups ( Bronson 1979 ), and genetic analyses have shown that gene … 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. … introduction to ethical theories
