Bred-back breeds are desirable in conservation biology, as they may fill an ecological gap left open by the extinction of a wild type due to human activities.As long as food preference, behaviour, robustness, defence against predators, hunting or foraging instincts and phenotype are the same as in the wild type, the bred-back phenotype will function similarly in the ecosystem.
In 2017, a breeding programme was established to revive the subspecies through back breeding the hybrids to regain their genetic purity. [140] As of 2025, 400 Floreana giant tortoises have been hatched on Santa Cruz Island with plans to release them into the wild on Floreana Island after the successful extirpation of invasive species.
Beginning in the 1930s, several attempts were made to develop horses that looked like tarpans through selective breeding, called "breeding back" by advocates. The breeds that resulted included the Heck horse , the Hegardt or Stroebel's horse [ fr ] , and a derivation of the Konik breed, all of which have a primitive appearance, particularly in ...
Heck cattle originated in Germany in the 1920s and 1930s in an attempt to breed back domestic cattle to their ancestral form: the aurochs (Bos primigenius primigenius). [10] In the first years of the Weimar Republic, the brothers Heinz and Lutz Heck independently started their extensive breeding-back programmes. [11]
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 ...
It is used in horticulture, animal breeding, and production of gene knockout organisms. Backcrossed hybrids are sometimes described with acronym "BC"; for example, an F1 hybrid crossed with one of its parents (or a genetically similar individual) can be termed a BC1 hybrid, and a further cross of the BC1 hybrid to the same parent (or a ...
