Selective breeding is the process of breeding plants and animals for particular traits. Typically, strains that are selectively bred are domesticated, and the breeding is sometimes done by a professional breeder.
Bred animals are known as breeds, while bred plants are known as varieties, cultigens, or cultivars. The cross of animal’s results is called a crossbreed, and crossbred plants are called hybrids. The term selective breeding has the same meaning as with artificial selection..
