Model. Evolution of avoidance of biparental inbreeding is most relevant in small or viscous populations where random mating among proximate individuals would commonly result in inbreeding (Jamieson et al. 2009; Bretman et al. 2011; Alho et al. 2012).Consequently, our model tracks individuals in a small focal population, which is implicitly embedded within and receives immigrants from a larger ...
