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 mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
Mules are more tolerant to heat than horses; horses are more efficient in cold weather. Mules, like donkeys, are more effective in deserts. Horses are more likely to suffer from exhaustion compared to mules. While mules are relatively slower than horses, they are much safer to ride. Mules consume less food than horses, and can live longer. [2]
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 ...
Hybrid incompatibility occurs when the offspring of two closely related species are not viable or suffer from infertility. Charles Darwin posited that hybrid incompatibility is not a product of natural selection, stating that the phenomenon is an outcome of the hybridizing species diverging, rather than something that is directly acted upon by selective pressures.

Both women and men are capable of performing extraordinary feats, but there are some things the females of our species do better. Here are 7 of them, according to science. Number 7.
Thanks to social media, people around the world have fallen in love with Fiona and Fritz at the Cincinnati Zoo and the adorable memes of baby Moo Deng. It’s easy to see why — baby hippos are ...
"In most fertile mule mares, the mare passes on a complete set of her maternal genes (i.e., from her horse/pony mother) to the foal; a female mule bred to a horse will therefore produce a 100% horse foal." With exactly two documented cases since the introduction of modern DNA testing the phrase "most fertile mule mares" is, at best, highly ...
