What Are the Results of Breeding a Donkey With a Horse?

The mating of a donkey and a horse results in a mule or a hinny. A mule is the offspring of a female horse and a male donkey, and a hinny is the offspring of a female donkey and a male horse.

Mules are more common than hinnies because it is not uncommon for a female donkey to have a miscarriage when bred with a stallion, if conception even occurs. As a rule, all mules and hinnies are sterile and unable to reproduce because these hybrid animals are the offspring of two distinct species. Although rare, there have been a small number of reported pregnancies in female mules and hinnies, according to A-Z Animals.
