Outbreeding, also called outcrossing, allogamy, or xenogamy, is the transfer of gametes from one individual to another, genetically different individual.

In biology, outbreeding depression happens when crosses between two genetically distant groups or populations result in a reduction of fitness. The concept is in contrast to inbreeding depression, although the two effects can occur simultaneously. Outbreeding depression is a risk that sometimes limits the potential for genetic rescue or augmentations. It is considered postzygotic response because outbreeding depression is noted usually in the performance of the progeny. WebHybrid vigor, also known as heterosis or outbreeding enhancement, is the phenomenon that a hybrid offspring has improved traits, such as growth rate, biomass, stress tolerance, and fertility [179, 180]. For example, hybrids of maize or domestic dog grow stronger and bigger than their parents [181].
