These include exaggerated physical features, inbreeding and inherited diseases. Particular dog breeds and pedigree dogs exist due to deliberate and selective breeding for specific traits by dog breeders.

Across 3 dairy breeds in the United States, VanRaden et al. (2011b) estimated a correlation ranging from 0.50 to 0.56 between pedigree- and genomic-based inbreeding coefficients. As shown by Pryce et al. (2012a), the correlation between A and G is dependent on the depth of the pedigree.

The Hollow is a 1975 documentary about the inbred hillbilly residents of an area of New York State in Saratoga County known informally as "Allentown" for reasons that soon become abundantly clear. It begins with the following text: Early in the 19th Century two families, the Allens and Kathans, settled in the Southern Adirondack Mountains of New York State.This is known as Inbreeding Depression and refers to a population decrease due to lack of healthy mates.
