Although incest is possible, Bufo americanus siblings rarely mate. Advertisement vocalizations by males appear to serve as cues by which females recognize their kin. In guppies, a post-copulatory mechanism of inbreeding avoidance occurs based on competition between sperm of rival males for achieving fertilization.
Active selection of sperm by females appears to occur in a manner that enhances female fitness. Outcrossing[ edit ] Mating with unrelated or distantly related members of the same species is generally thought to provide the advantage of masking deleterious recessive mutations in progeny  and see Heterosis.
Vertebrates have evolved numerous diverse mechanisms for avoiding close inbreeding and promoting outcrossing  and see Inbreeding avoidance. Outcrossing as a way of avoiding inbreeding depression, has been especially well studied in birds.
