donkeyhorse
A donkeyhorse is a hybrid animal resulting from the crossbreeding of a male donkey and a female horse. This offspring is a type of mule, specifically a hinny. Unlike a mule, which is the offspring of a male horse and a female donkey, a hinny has a different set of parentage. Donkeyhorses are typically sterile, meaning they cannot reproduce. They share characteristics of both parent species. From their horse mothers, they tend to inherit more horse-like body conformation, including longer legs and a more refined build. From their donkey fathers, they often inherit the donkey's characteristic bray, smaller head, and sometimes longer ears, although generally shorter than those of a pure donkey. Donkeyhorses are known for their hardiness, endurance, and sure-footedness, traits inherited from both donkeys and horses. They have historically been used as work animals for centuries, valued for their strength and ability to carry heavy loads in challenging terrain. Their temperament is often described as calm and intelligent, though they can also be stubborn, a trait sometimes attributed to their donkey ancestry. The breeding of donkeyhorses is less common than that of mules, partly due to the differing chromosome numbers of horses and donkeys, which can make conception and gestation more difficult.
