WebDec 14, 2015 · Inbreeding results in homozygosity, which increases the chances of offspring being affected by recessive or deleterious traits. Heterosis The benefits of hybridisation, through the exploitation of heterosis are well proven through scientific experiment and commercial recording. 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.
