Breeding back is a form of artificial selection by the deliberate selective breeding of domestic (but not exclusively) animals, in an attempt to achieve an animal breed with a phenotype that resembles a wild type ancestor, usually one that has gone extinct.
In Singapore, the local population went locally extinct in the 1960s, but bounced back in the 1990s and hornbills are now widespread around the island. [15] Conservation efforts such as captive breeding and reintroduction are currently in practice. Breeding in captivity has so far shown a low success rate.
Breeding back, a breeding effort to re-assemble extinct breed genes; Breeding pair, bonded animals who cooperate to produce offspring; Breeding program, a planned breeding of animals or plants; Breeding season, the period during each year when a species reproduces; Captive breeding, raising plants or animals in zoos or other controlled conditions
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 ...
The Pyrenean ibex, also known as the bouquetin (French) and bucardo (Spanish), is the only animal to have survived de-extinction past birth through cloning.. De-extinction (also known as resurrection biology, or species revivalism) is the process of generating an organism that either resembles or is an extinct species. [1]
Selective breeding has been responsible for large increases in productivity. For example, in 2007, a typical broiler chicken at eight weeks old was 4.8 times as heavy as a bird of similar age in 1957, [ 36 ] while in the thirty years to 2007, the average milk yield of a dairy cow in the United States nearly doubled.

Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities.
