Biologists have long recognized that inbred individuals (those whose parents are closely related) often have lower fitness than the offspring of unrelated parents (Darwin, 1868; Ives and Whitlock, 2002).The cumulative effects of inbreeding on individual fitness can reduce the population growth rate and the probability of persistence (O'Grady et al., 2006; Kenney et al., 2014).Esther Renee Adams, "Mamaw," was laid to rest in her own home.

Definition of consanguinity. In clinical genetics, a consanguineous marriage is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156 (Bittles 2001), where (F) represents a measure of the proportion of loci at which the offspring of a consanguineous union is expected to inherit identical gene ...Fertility rates are affected by inbreeding, and already, Holstein fertility has dropped significantly.
