Inbreeding in the united states.
Inbreeding from the method of average relationships for missing ancestors was 2.75 ± 1.06, 3.10 ± 2.21, and 2.89 ± 2.37 for the same groups. Registered English and Scottish were over 97% and over 89% complete, respectively. Inbreeding depression in days to first service and summit yield was estimated from both methods.

Inbreeding often imposes net fitness costs, 1-5 leading to the expectation that animals will engage in inbreeding avoidance when the costs of doing so are not prohibitive. 4-9 However, one recent meta-analysis indicates that animals of many species do not avoid mating with kin in experimental settings, 6 and another reports that behavioral inbreeding avoidance generally evolves only when kin ...
