A mule is a animal hybrid of a female horse (a mare) and a male donkey (a jack). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a female donkey (a jenny) and a male horse (a stallion).
A mule is generally sterile. Although it is extremely unlikely for a mule to become pregnant (less than 300 reported cases worldwide), it is possible.
