Outcrossing
technique of crossing between different breeds
Outcrossing is a term used in genetics for the mating of unrelated individuals in a population or species. It was originally used for the crossing of an inbred strain with the wild type.[1] Hybrid vigour is the great improvement in fitness which usually occurs as a result of outcrossing a previously inbred line.
Outcrossing leads to random mating, whereas mating of relatives leads to inbreeding.
