The mule is a domestic equine hybrid between a donkey and a horse.It is the offspring of a male donkey (a jack) and a female horse (a mare). [1] [2] 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 male horse ...
A male donkey (jack) crossed with a female horse produces a mule, while a male horse crossed with a jenny produces a hinny. Horse–donkey hybrids are almost always sterile because of a failure of their developing gametes to complete meiosis. [88] The lower progesterone production of the jenny may also lead to early embryonic loss. In addition ...
Horses can breed with Przewalski's horse to produce fertile hybrids. Mule, a cross of female horse and a male donkey. Hinny, a cross between a female donkey and a male horse. Mules and hinnies are examples of reciprocal hybrids. Kunga, a cross between a donkey and a Syrian wild ass. Zebroids. Zeedonk or zonkey, a zebra/donkey cross. Zorse, a ...
A hinny is a domestic equine hybrid, the offspring of a male horse (a stallion) and a female donkey (a jenny). It is the reciprocal cross to the more common mule, which is the product of a male donkey (a jack) and a female horse (a mare).
The Baudet du Poitou, also called the Poitevin or Poitou donkey, is a French breed of donkey. It is one of the largest breeds, and jacks (donkey stallions) were bred to mares of the Poitevin horse breed to produce Poitevin mules, which were formerly in worldwide demand for agricultural and other work.

Another point of view is that a breed is consistent enough in type to be logically grouped together and when mated within the group produce the same type. [5] When bred together, individuals of the same breed pass on these predictable traits to their offspring, and this ability – known as "breeding true" – is a requirement for a breed.
For example, the cross between a male zebra and a female horse is a zorse. A cross between a male zebra and a female donkey is a zonkey. Horse-donkey crosses are an exception to this naming convention. A mule is the cross between female horse and male donkey. A hinny is the cross of male horse and female donkey; mules and hinnies are reciprocal ...
