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 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).
This horse's dorsal stripe is most likely caused by non-dun 1. Less distinct primitive markings can also occur on non-dun horses, even in breeds which are not known to have any dun individuals. The most common primitive marking found is a dorsal stripe. [1] Most non-dun horses do not have darker primitive markings, but some do.
A mule (horse and donkey hybrid) Equine species can crossbreed with each other. The most common hybrid is the mule, a cross between a male donkey and a female horse. With rare exceptions, these hybrids are sterile and cannot reproduce. [28] A related hybrid, a hinny, is a cross between a male horse and a female donkey. [29]
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. [86] The lower progesterone production of the jenny may also lead to early embryonic loss. In addition ...
The hybrid offspring of a male donkey and a horse mare. Almost always sterile. The hybrid with the reverse parentage (and somewhat different appearance and characteristics) is a hinny. [1]: 139 Mules are noted for their sure-footedness. [8]: 326–327 muster (AU/NZ) The assembling or roundup of livestock. [41]: 1147 See also drift and roundup.
The American Mammoth Jackstock is a breed of North American donkey, descended from large donkeys imported to the United States from about 1785. George Washington, with Henry Clay and others, bred for an ass that could be used to produce strong work mules. Washington was offering his jacks for stud service by 1788.
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 ...
