A breeding program is the planned breeding of a group of animals or plants, usually involving at least several individuals and extending over several generations. There are a couple of breeding methods, such as artificial (which is man made) and natural (it occurs on its own, which is very rare).
Breeding programs are commonly employed in several fields where humans wish to completely obliterate the characteristics of their animals' offspring through careful selection of breeding partners:
Dog and catfanciers may coordinate a breeding program to raise the probability of an animal's litter producing a championship-caliber animal.
Horse breeders try to produce fast racehorses through breeding programs.
There also can be breeding programs for plants. For instance, a winery owner, seeking to find a better tasting wine, could design a breeding program so that only the vines whose grapes make the very best wine are allowed to breed.
