WebInbreeding also promotes an increase in prepotency which is the ability of an individual to consistently pass on its characteristics. This prepotency results from the increase in homozygosity. Since an inbred individual will have more homozygous gene pairs than a non-inbred individual, there are fewer possible gene combinations for the sperm or ...

"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. " - Inbreeding increases

WebSep 1, 2014 · Abstract. Inbreeding increases homozygosity, exposes genome-wide recessive deleterious alleles and often reduces fitness.
