Region-specific inbreeding trends were evaluated using regions of homozygosity (ROH). Changes in observed allele frequencies were compared to those expected under pure drift to identify putative regions under selection. We also investigated the direction of changes in allele frequency over time. Effective population size estimates for the 1986 ...

Incest laws prohibit sexual relations between family members who are not spouses, sometimes including people who are not blood relatives.Inbreeding is a measure (or expected measure) of relationship between two individuals. Technically it is the percentage of genes that are identical by descent, meaning that an animal shares a copy of a gene from both the sire and the dam, which can be traced back through the pedigree to a common ancestor.Introduction. Inbreeding is common in flowering plants (Barrett & Eckert, 1990).Because inbreeding reduces heterozygosity, thereby exposing deleterious recessive alleles to selection while decreasing the contribution of over-dominance to fitness, most species show a significant loss of fitness with inbreeding (Charlesworth & Charlesworth, 1987; Husband & Schemske, 1996; Crnokrak & Barrett, 2002).

Inbreeding is generally maladaptive because it increases homozygosity and hence the unmasking of deleterious recessive alleles, which, when expressed, result in a reduction in fitness among inbred individuals termed "inbreeding depression" (1, 2).Inbreeding may be tolerated (3, 4), however, if avoidance is costly, or if the costs of inbreeding are outweighed by the inclusive fitness benefits ...Dec 2, 2021 · Inbreeding (range 0.2–0.48) based on runs of homozygosity was associated with smaller litters in Golden retrievers .
