Breeding two animals together that have no common ancestry. Compare to Inbreeding and Linebreeding. For more information: Inbreeding vs. Linebreeding.
mating two individuals of the same breed that are sufficiently unrelated that the IC of the progeny is lower than the average of the parents.
The breeding of one registered breed to another, resulting in a registerable hybrid breed. Also refers to the breeds allowable in the background of a registered hybrid breed.
The act of maintaining genetic variability in mutant animal populations by means of breeding into the population unrelated animals and later recovering the recessive traits in the F2 generation.
Mating of individuals that are less closely related than the average of the breed. Commercial breeders and some purebred breeders should be outcrossing by periodically adding new sires that are unrelated to their herd. This outcrossing should reduce the possibility of loss of vigor due to inbreeding.
The mating of unrelated individuals of the same breed.
mating between different individuals/species.
Mating of parents that are several generations apart.
Outcrossing is the practice of introducing unrelated genetic material into a breeding line. It increases genetic diversity, thus reducing the probability of all individuals being subject to disease or reducing genetic abnormalities(only within the first generation).
