Tree breeding is the application of genetic, reproductive biology and economics principles to the genetic improvement and management of forest trees. In contrast to the selective breeding of livestock, arable crops, and horticultural flowers over the last few centuries, the breeding of trees, with the exception of fruit trees, is a relatively recent occurrence.
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.
Cooperative breeding encompasses a wide variety of group structures, from a breeding pair with helpers that are offspring from a previous season, [2] to groups with multiple breeding males and females (polygynandry) and helpers that are the adult offspring of some but not all of the breeders in the group, [3] to groups in which helpers ...
Information about a species' reproductive biology may be critical to the success of a captive breeding program. [2] [3] [4] In some cases a captive breeding program can save a species from extinction, [5] but for success, breeders must consider many factors—including genetic, ecological, behavioral, and ethical issues. Most successful ...
Horse breeders try to produce fast racehorses through breeding programs. Conservationists use breeding programs to try to help the recovery of endangered species by preserving the existing gene pool and preventing inbreeding .
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
These hybrids were small, agile, and trainable, and had excellent noses. The jackal–dog hybrids were bred together for seven generations to establish the breed. The result was an easily trainable dog with a superior sense of smell, called "Sulimov dogs" after their breeder. [citation needed] As described by Sulimov:
A breeder is usually a purebred animal, bred with the intent of producing purebred, or even show-quality animals. However, in some cases, a breeding animal is crossbred with another breed or a mixed breed with the intent of combining aspects of two or more different breeds.
