Now we know ...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 ...Approximately 27% of people in the United States and between 8% and 10% of the world's population have blue eyes.
