The donkey or ass (Equus asinus) is a domesticated animal of the horse family, Equidae. The wild ancestors of the donkey are African. Donkeys are typical equids, generally smaller than the domestic horse, though mammoth jacks can be as large as 17 hands (170cm at the shoulder). They come in a variety of sizes and breeds just like the horse family, ranging in size from miniatures, standard (pony size) to mammoth (full grown horse sizes). They have long ears and a "broomtail" similar to a cow's tail.

A male donkey (jackass or jack) can be crossed with a female horse to produce a mule. A male horse can be crossed with a female donkey (jennet or jenny) to produce a hinny. These hybrids are almost always sterile because horses have 64 chromosomes and donkeys have 62, producing offspring with 63 chromosomes. Due to different mating behavior, mules are much more common than hinnies: before the male mounts the female, the latter kicks vigorously at the former. In donkeys, this behavior is much more intense; thus, a stallion will often simply not mate with a jenny because he is taking more of a beating than he is expecting to get and will refuse to mate. Moreover, mules are more easily handled and also physically stronger than hinnies, making them more desirable for breeders to produce.
