WebNov 21, 2011 · Inbreeding is a phenomenon frequently associated with small populations and can occur in a large population as a form of nonrandom mating when the frequency of consanguineous matings is higher than that expected by chance.

The opposite effect, inbreeding depression, results from repeated self-pollination and leads to a reduction in vigor. A popular explanation for this reaction is the homozygosis of recessive, slightly deleterious alleles upon inbreeding.

WebSelfing leads to progressive homozygosis, which in turn unmasks deleterious recessive mutations and often results in a decline in fitness called inbreeding depression [44]. To survive, an incipient selfing population must rid itself of residual deleterious mutation through a process called purging. hiking yosemite the end of marchWebA transgenic individual can later be bred to homozygosity and maintained as an inbred line to reduce the need to confirm the genotype of each individual.
