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]
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 ...
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.
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.
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 .
Other breeders may use the same first letter to designate all the foals born on the farm in a given year. Some breeders create a name that incorporates or acknowledges the names of the sire, dam or other forebears. For example, the famous cutting horse Doc O'Lena was by Doc Bar out of Poco Lena, a daughter of Poco Bueno.
In a form of reciprocal evolution humans have influenced these plants as much as the plants have influenced the people that consume them, is known as coevolution. [ 21 ] Selective plant breeding is also used in research to produce transgenic animals that breed "true" (i.e., are homozygous ) for artificially inserted or deleted genes.
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 ...
