Heterosis - hybrid vigor - is the reversal of the loss of vigor that defines inbreeding depression as a result of an increase in genetic heterozygosity. 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.
