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.
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 ...
Introgression is gene transfer among taxa and is a result of hybridization, followed by repeated backcrossing with parental individuals. Introgressive hybridization occurs often in plants, and results in increased genetic variation, which can facilitate rapid response to climate change. [3]
Hybrid speciation results in reproductive isolation against both parent species and genomes that evolve independently from those of the parent species. Introgressive hybridization can transfer important novel variants into genomes of a species that remains distinct from the other taxa in spite of occasional gene flow.
Anderson published Introgressive Hybridization in 1949, describing gene transfer between hybridizing forms, [5] and the role of introgression in speciation. [20] He also wrote the popular science book Plants, Man, and Life (1952), described by one reviewer as "a book every botanist and anthropologist should read". [21]
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.

An ornamental lily hybrid known as Lilium 'Citronella' [1] This is a list of plant hybrids created intentionally or by chance and exploited commercially in agriculture or horticulture. The hybridization event mechanism is documented where known, along with the authorities who described it.
