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 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.

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 ] .
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 ...
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 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]
