Inbreeding avoidance mechanisms have evolved in response to selection against inbred offspring. Inbreeding avoidance occurs in nature by at least four mechanisms: kin recognition, dispersal, extra-pair/extra-group copulations, and delayed maturation/reproductive suppression.
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] By analogy, the term is used in human reproduction , but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious recessive traits resulting from ...

The mechanisms of reproductive isolation are a collection of evolutionary mechanisms, behaviors and physiological processes critical for speciation.They prevent members of different species from producing offspring, or ensure that any offspring are sterile.
Culling is: ... the rejection or removal of inferior individuals from breeding. The act of selective breeding. As used in the practice of breeding pedigree cats, this refers to the practice of spaying or neutering a kitten or cat that does not measure up to the show standard (or other standard being applied) for that breed.
However animals often do not avoid inbreeding. [7] Among animals, inbreeding avoidance is highly variable. [8] Inbreeding avoidance through mate selection appears to evolve only when there is both a risk of inbreeding depression and there also are frequent encounters between potential sexual partners that are related to each other.

Dominant breeding males and females often have higher glucocorticoid levels among the dwarf mongoose (Helogale parvula), African wild dogs (Lycaon pictus) and gray wolves (Canis lupus) in which older and heavier individuals make up the breeding individuals in the group with younger individuals helping to raise their pups.
