WebInbreeding increases homozygosity B Inbreeding is essential to evolve pure lines in any animal C Inbreeding selects harmful recessive genes that reduce fertility and productivity D Inbreeding helps in accumulation of superior genes and elimination of undesirable genes Medium NEET Solution Verified by Toppr Correct option is C) WebIncreased homozygosity—the inheritance of two identical alleles at a certain genetic locus—is the effect of this. Inbreeding can increase homozygosity, however this can have …
WebInbreeding increases homozygosity and helps in developing pure lines. But continued inbreeding results in reduced fertility and productivity in animals. This is called inbreeding depression. This can be overcome by crossing these animals with unrelated superior animals of the same breed having no common ancestors. This is called out-crossing. WebInbreeding is a cumulative phenomenon and in the course of successive generations it increases homozygosity by 50% and reduces heterozygosity by 50% in F1, 25% in F2, …
WebThe basic genetic consequence of inbreeding is to promote what is technically known as homozygosity. This means there is an increase in the frequency of pairing of similar genes. ...

WebHowever, inbreeding in the moose population manifests in the form of intermediate-length runs of homozygosity suggestive of historical inbreeding and purging, contrasting with the long runs of homozygosity observed in the smaller wolf population. Using simulations, we confirm that substantial purging has likely occurred in the moose population.

Pedigrees can be incomplete or have errors, which can lead to large under-estimation of COI. Genetic COI becomes more valuable to a breeder when considering breeding pairs because it is a direct measure of realized inbreeding.
