WebOutbreeding depression occurs when very distantly related conspecific individuals are mated or when members of two different but related species hybridize. The male and female genomes are sufficiently different to produce a hybrid with genetic disorders. WebFor example, the megapodes (large, ground-dwelling birds such as the Australian malleefowl, Leipoa ocellata) construct a large mound of vegetation and soil or sand to lay their eggs in. Megapodes often reuse the same mound for many years, only abandoning it when it is damaged beyond repair, or due to disturbance.
