The aim of breeding back programs is to restore the wild traits which may have been unintentionally preserved in the lineages of domesticated animals. Commonly, not only the new animal's phenotype, but also its ecological capacity, are considered in back-breeding projects, as hardy, "bred back" animals may be used in certain conservation ...
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 ...
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.
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]
The Heck horse was created by the German zoologist brothers Heinz Heck and Lutz Heck, director of the Berlin Zoo, at the Tierpark Hellabrunn (Munich Zoo) in Germany in their attempt to breed back the tarpan. [2] [5] The Hecks believed they could recreate the extinct tarpan subspecies by back breeding living descendants. [6]
Down below, the phenotypic and ecologic breeding target, the Aurochs. The Tauros Programme , formerly known as TaurOs Project , is a cooperation between the Dutch foundation Stichting Taurus and universities such as the Wageningen University and Research Centre [ citation needed ] .
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 ...
