The [[breeder]] (or group of breeders) who initially establishes a breed does so by [[Selective breeding|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. These animals are referred to as [[foundation stock]]. Furthermore, the breeder mates the most desirable representatives of the breed from his or her point of view, aiming  to pass such characteristics to their [[Offspring|progeny]]. This process is known as [[selective breeding]]. A written description of desirable and undesirable breed representatives is referred to as a [[breed standard]].
