WebInbreeding is the mating of relatives. Genetically, all inbreeding does is increase homozygosity in the offspring (this means inbreeding also decreases heterozygosity in the offspring by an equal amount; in this manual, inbreeding will be defined and discussed as it relates to homozygosity). WebMar 15, 2016 · Decreasing fitness with increasing inbreeding is a widespread phenomenon (), which occurs because mating between relatives increases homozygosity at loci carrying rare recessive deleterious alleles or exhibiting overdominance ().The magnitude of inbreeding depression is relevant to many disciplines within biology, including the …
