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.
If the breeding is for a purebred animal that will be used for exhibition or future breeding (pets or livestock), the animal must be registered and conform to the criteria laid out for that breed in a breed standard kept by a central authority, such as a kennel club for dogs. In addition, the breed club, kennel club, or other governing ...
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Outcrossing can be a useful technique in animal breeding.The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits, whether one outcrosses, line breeds or inbreeds.
Most mating done by purebred breeders is linebreeding which is the mating of animals of different families within the same breed to bring in desirable traits that are not present in the original animals. [11] Unlike commercial producers, purebred breeders cannot use crossbreeding as it would dilute the breed's purity, resulting in a mixed breed ...
Line breeding is differentiated from inbreeding by excluding pairings between parents and offspring, and between full siblings. Outcrossing is the planned breeding between two unrelated dogs, used to increase genetic diversity in a breed and decrease genetic issues or abnormalities inherited from line breeding or inbreeding.
Mules are F1 hybrids between horses (mares) and donkeys (jacks); the opposite sex cross results in hinnies. However, such offspring are almost always sterile. Today, certain domesticated–wild hybrid breeds, such as the Bengal cat and the Savannah cat, are classified by their filial generation number. An F1 hybrid Savannah cat is the result of ...
A simplification of an allopatric speciation experiment where two lines of fruit flies are raised on maltose and starch media. Laboratory experiments of speciation have been conducted for all four modes of speciation: allopatric, peripatric, parapatric, and sympatric; and various other processes involving speciation: hybridization, reinforcement, founder effects, among others.
