WebInbreeding increases homozygosity, i.e., state of possessing two identical alleles, one inherited from each parent. It is necessary if we want to evolve a pureline in any animal. Inbreeding exposes harmful recessive genes that are eliminated by selection. It also helps in accumulation of superior genes and elimination of less desirable genes.

WebInbreeding can increase homozygosity, however this can have unfavourable effects on the population’s genetic diversity and the expression of harmful recessive genes. Mating … 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.

WebDec 30, 2016 · After the first "inbreeding" generation, we'll have: 25% AA 50% Aa 25% aa. So, 50% of heterozygotes.
