Inbreeding and homozygosis

WebInbreeding is the mating of individuals that are related. In the strict sense, all members of a breed are related. As a result, any seedstock producer is practicing some inbreeding. Therefore, we generally reserve the term inbreeding for the mating of animals that are more closely related than the average of the breed.

WebThe number of inbreeding generations required to produce homozygotes may be reduced if the more homozygous individuals in each breeding generation are selected phenotypically in the segregating progenies for further inbreeding. To demonstrate this, inbred lines and their F1, S1, and S2 progenies were studied for number of days from planting to anthesis, plant … WebClose inbreeding leads to homozygosis and, as a rule, to a decline in fit-ness. The latter-inbreeding depression-results in part from the expres-sion of deleterious recessive mutations that ordinarily are concealed by more nearly normal, dominant alleles.
