Breeding pair Breeding pair is a pair of animals which cooperate over time to produce offspring with some
Breeding back for a breeding back attempt to actually recreate an extinct wild type that is the breeding target, as an extinct wild type cannot be resurrected via selective breeding alone. Furthermore, even the outward authenticity of a bred-back type depends on the quality of the stock used as the foundation of the project. As a result, some breeds, like Heck cattle, are at best a vague look-alike of the extinct wildtype aurochs, according to the literature. It is the target of breeding back to restore the wild traits that may have been preserved in domestic animals within one breeding lineage. Commonly,
