Departures from HW proportions in populations can occur for three principal reasons. First, parents might be related, leading to inbreeding. Inbreeding decreases the proportion of heterozygotes, with a compensatory increase in homozygotes. Second, the population can be subdivided, as in the United States.

The Whitaker family from Odd, West Virginia, is arguably the most famous inbred family in the United States.

Since inbreeding depression negatively affects plant size and herbivore resistance, inbreeding may modify the evolution of the interaction between V. hirundinaria and its specialist folivore. The results further suggest that herbivory may contribute to the maintenance of a mixed mating system of the host plants by selecting for outcrossing and reduced susceptibility to herbivore ...Inbreeding depression (reduced fitness of individuals with related parents) has long been a major focus of ecology, evolution, ...
