Cloning is defined as the process of creating a genetically identical copy of another cell or organism (i.e., bacteria, plant or animal) through non-sexual means. In the equine world, cloning refers to the advanced assisted reproduction technique (like embryo transfer) and subsequent production of a foal that has the exact same DNA as the donor horse, be it mare, stallion, or gelding. Successfully cloned animals include the rhesus monkey, the gaur and banteng (endangered bovine species), cattle, cats, mules, water buffalo, and horses.

This free fact sheet offers an overview in cloning, including how animals are cloned, the progress of cloning in the equine world, why horses and mules are cloned, and how the process of registering a horse or mule has been affected by cloning.
