Hybridization sometimes results in introgression, which can occur in response to habitat disturbance that puts plant species into contact with each other. [2] Introgression is gene transfer among taxa and is a result of hybridization, followed by repeated backcrossing with parental individuals.
A form of hybrid speciation that is relatively common in plants occurs when an infertile hybrid becomes fertile after doubling of the chromosome number. Hybridization without change in chromosome number is called homoploid hybrid speciation. [1] This is the situation found in most animal hybrids.
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.

Ligers and tigons (crosses between a lion and a tiger) and other Panthera hybrids such as the lijagulep. Species P. tigris. A hybrid between a Bengal tiger and a Siberian tiger is an example of an intra-specific hybrid. Family Canidae
Introgressive hybridization, also known as introgression, is the flow of genetic material between divergent lineages via repeated backcrossing. In plants, this backcrossing occurs when an F 1 {\displaystyle F_{1}} generation hybrid breeds with one or both of its parental species.
Hybridization without change in chromosome number is called homoploid hybrid speciation. It is considered very rare but has been shown in Heliconius butterflies [ 83 ] and sunflowers . Polyploid speciation, which involves changes in chromosome number, is a more common phenomenon, especially in plant species.
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before ...
Hybrid zones can form from secondary contact. A hybrid zone exists where the ranges of two interbreeding species or diverged intraspecific lineages meet and cross-fertilize. . Hybrid zones can form in situ due to the evolution of a new lineage [1] [page needed] but generally they result from secondary contact of the parental forms after a period of geographic isolation, which allowed their ...
