Purebred are those animals that have been bred-up to purebred status as a result of using full blood animals to cross with an animal of another breed. Artificial breeding via artificial insemination or embryo transfer is often used in sheep and cattle breeding to quickly expand, or improve purebred herds.
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
Breeding stock is a group of animals used for the purpose of planned breeding. When individuals are looking to breed animals, they look for certain valuable traits in purebred animals, or may intend to use some type of crossbreeding to produce a new type of stock with different, and presumably superior abilities in a given area of endeavor. For ...
This example shows three different breeds of the domestic pig, which all vary widely in appearance. The breeder (or group of breeders) who initially establishes a breed does so by selecting individual animals from within a gene pool that they see as having the necessary qualities needed to enhance the breed model they are aiming for.
Some examples are problems with breathing in the Pug breed and Pekingese breed, spinal problems in the Dachshund breed, and Syringomyelia in the Cavalier King Charles Spaniel breed. Some scientific researchers argue that advances in artificial reproduction technology for the purposes of dog breeding can be helpful, but also have "detrimental ...
Subsequent generations may see a purebred animal crossed back on a crossbred, creating a 75/25 cross, [7] or a BC1 or F1b "backcross." [citation needed] The breeding of two crossbreeds of the same combination of breeds, creating an F2 cross, an animal that is still a 50–50 cross, but it is the second filial generation of the combination.

The deliberate exploitation of selective breeding to produce desired results has become very common in agriculture and experimental biology. Selective breeding can be unintentional, for example, resulting from the process of human cultivation; and it may also produce unintended – desirable or undesirable – results.
Crossbreeding, the process of breeding an animal with purebred parents of two different breeds, varieties, or populations; Mating; Preservation breeding, a selection practice to preserve bloodlines; Selective breeding, an animal selection practice to encourage chosen qualities; Smart breeding, a plant selection practice to encourage chosen ...
