WebAug 1, 2024 · The regression of performance on genomic estimates of inbreeding have been conducted, and unfavorable estimates per 1% increase in genomic-based inbreeding have been found; these are generally comparable or slightly larger than pedigree-based estimates ( Bjelland et al., 2013; Pryce et al., 2014 ). 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.
