out breeding?

Outbreeding is a phenomenon where individuals within a species will tend to breed with others who are neither close relatives nor distant genetic relations, but a middle ground of the two. The process involves what is known as kin recognition, which all species appear to have, including humans. Kin recognition is an innate ability to recognize that members of a species are genetically closely related, and therefore avoid breeding with them to avoid genetic deformities from arising in the offspring.
