In South America, mouflon have been introduced into central Chile and Argentina. Since the 1980s, they have also been successfully introduced to game ranches in North America for the purpose of hunting; however, on game ranches, purebreds are rare, as mouflon interbreed with domestic sheep and bighorn
European Endangered Species Programme loss of genetic variability, and accumulation of deleterious mutations. These problems can easily result in loss of original wild traits, and in the expression of heritable abnormalities. If what was once a pure, wild population of animals deteriorates through generations of uncontrolled breeding into inferior or partially domesticated stock, then the animals are no longer suitable for any conservation effort, and the zoos have failed to perform an important educational task. The effects of breeding captive populations of wild animals over periods of many generations have been well studied. Based on these studies and genetic theory, guidelines for breeding such
