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 ...
Hybrid incompatibility is a phenomenon in plants and animals, wherein offspring produced by the mating of two different species or populations have reduced viability and/or are less able to reproduce. Examples of hybrids include mules and ligers from the animal world, and subspecies of the Asian rice crop Oryza sativa from the plant world ...
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.
In the wild, the horses and donkeys ignore each other and do not cross. In order to obtain mules or hinnies it is necessary to train the progenitors to accept copulation between the species or create them through artificial insemination. The sterility of many interspecific hybrids in angiosperms has been widely recognised and studied. [33]
The most common hybrid is the mule, a cross between a "jack" (male donkey) and a mare. A related hybrid, a hinny, is a cross between a stallion and a "jenny" (female donkey). [150] Other hybrids include the zorse, a cross between a zebra and a horse. [151] With rare exceptions, most hybrids are sterile and cannot reproduce. [152]
It can't be burned or buried. Soon, a waste management plant will turn the waste into glass, which can be stored away for thousands of years. It's a slow, costly process.
WASHINGTON — Conservative gadfly Dinesh D’Souza’s film and book “2000 Mules,” which pushes false conspiracies about voter fraud in the 2020 presidential election, has been removed from ...
Pregnant male seahorse. Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes and males producing smaller gametes ().
