In its common modern meaning, a mule is the offspring of a male donkey and a female horse.
This can be compared with the offspring of a male horse with a female donkey, called a hinny.
The term "mule" was formerly applied to the offspring of any two creatures of different species – in modern usage, a "hybrid".
The mule, easier to breed and usually larger in size than a hinny, has monopolised the attention of breeders.
The chromosome match-up more often occurs when the jack (male donkey) is the sire and the mare (female horse) is the dam.
Mules and hinnies are almost always sterile..
