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 plants, hybridization mostly generates speciation events, [5] and commonly produces polyploid species. Factors like polyploidy events also plays significant factors for understanding the hybridization events (Example: an F1 hybrid of Jatropha curcas x Ricinus communis ), [ 6 ] because these polyploids tend to have an advantage for the early ...
Genetics are more variable and malleable in plants than in animals, probably reflecting the higher activity level in animals. [citation needed] Hybrids' genetics will necessarily be less stable than those of species evolving through isolation, which explains why hybrid species appear more common in plants than in animals.
The naming of hybrid animals depends on the sex and species of the parents. The father giving the first half of his species' name and the mother the second half of hers. (I.e. a pizzly bear has a polar bear father and grizzly bear mother whereas a grolar bear's parents would be reversed.)
Fused protoplast (left) with chloroplasts (from a leaf cell) and coloured vacuole (from a petal) Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid.

Hybridization is an important means of speciation in plants, since polyploidy (having more than two copies of each chromosome) is tolerated in plants more readily than in animals. [ 80 ] [ 81 ] Polyploidy is important in hybrids as it allows reproduction, with the two different sets of chromosomes each being able to pair with an identical ...
A hybrid animal is one with parentage of two separate species, differentiating it from crossbred animals, which have parentage of the same species. Hybrids are usually, but not always, sterile. [5] One of the most ancient types of hybrid animal is the mule, a cross between a female horse and a male donkey.
Selfing is also expected to increase the likelihood of establishment for homoploid hybrids according to a modelling study, [150] and the higher probability of selfing may contribute to the higher frequency of hybrid species in plants. Fungal hybridization may result in asexual hybrid species, as Epichloe fungi where hybrids species are asexual ...
