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.
Variety is defined in the code as follows: "Variety (varietas) the category in the botanical nomenclatural hierarchy between species and form (forma)". The code acknowledges the other usage as follows: "term used in some national and international legislation for a clearly distinguishable taxon below the rank of species; generally, in ...
The hybrid grape variety Marechal Foch. Hybrid grapes are grape varieties that are the product of a crossing of two or more Vitis species. This is in contrast to crossings between grape varieties of the same species, typically Vitis vinifera, the European grapevine. Hybrid grapes are also referred to as inter-species crossings or "Modern ...
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.
Hybridity is a cross between two separate races, plants or cultures. [5] A hybrid is something that is mixed, and hybridity is simply mixture. Hybridity is not a new cultural or historical phenomenon. It has been a feature of all civilizations since time immemorial from the Sumerians through the Egyptians, Greeks and Romans to the present.
Failure to produce a hybrid may be due to pre- or post-fertilization incompatibility. If fertilization is possible between two species or genera, the hybrid embryo may abort before maturation. If this does occur the embryo resulting from an interspecific or intergeneric cross can sometimes be rescued and cultured to produce a whole plant.
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare.
The best known hybrid from micrantha is the Key lime (or Mexican lime), derived from the breeding of a male citron and a female micrantha. Several citrus varieties are Ichang papeda/mandarin crosses (for which Swingle coined the term ichandarin [25]), including Sudachi and Yuzu (which also includes smaller contributions from pomelo and kumquat ...
