hybrid
/huy"brid/, n.
1. the offspring of two animals or plants of different breeds, varieties, species, or genera, esp. as produced through human manipulation for specific genetic characteristics.
2. a person or group of persons produced by the interaction or crossbreeding of two unlike cultures, traditions, etc.
3. anything derived from heterogeneous sources, or composed of elements of different or incongruous kinds: a hybrid of the academic and business worlds.
4. a word composed of elements originally drawn from different languages, as television, whose components come from Greek and Latin.
adj.
5. bred from two distinct races, breeds, varieties, species, or genera.
6. composite; formed or composed of heterogeneous elements.
7. composed of elements originally drawn from different languages, as a word.
[1595-1605; < L hybrida, hibrida a crossbred animal]
Syn. 5. HYBRID, MONGREL refer to animals or plants of mixed origin. HYBRID is the scientific term: hybrid corn; a hybrid variety of sheep. MONGREL, used originally of dogs to denote the offspring of crossings of different breeds, is now extended to other animals and to plants; it is usually deprecatory, as denoting mixed, nondescript, or degenerate breed or character: a mongrel pup.
Ant. 5. purebred, thoroughbred.

Offspring of parents that differ in genetically determined traits (see genetics).

The parents may be of two different species, genera, or (rarely) families. The terms "mongrel" and "crossbreed" refer usually to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species. Because of basic biological incompatibilities, sterile hybrids (those that cannot produce living young) such as the mule (a hybrid between a jackass and a mare) commonly result from crosses between species. Some species hybrids, however, are fertile and can be sources for the formation of new species. Many economically or aesthetically important cultivated plants (e.g., bananas, coffee, peanuts, dahlias, roses, bread wheats, alfalfa, etc.) originated through natural or artificially induced hybridization. Hybridization is important biologically because it increases necessary genetic variation within a species.

      offspring of parents that differ in genetically determined traits. The parents may be of different species, genera, or (rarely) families. The term hybrid, therefore, has a wider application than the terms mongrel or crossbreed, which usually refer to animals or plants resulting from a cross between two races, breeds, strains, or varieties of the same species. There are many species hybrids in nature (in ducks, oaks, blackberries, etc.), and, although naturally occurring hybrids between two genera have been noted, most of these latter result from human intervention.

      Because of basic biological incompatibilities, sterile hybrids (those incapable of producing living young) such as the mule (a hybrid between a jackass and a mare) commonly result from crosses between species. Some interspecific hybrids, however, are fertile and true breeding. These hybrids can be sources for the formation of new species. Many economically or aesthetically important cultivated plants (bananas, coffee, peanuts, dahlias, roses, bread wheats, alfalfa, etc.) have originated through natural hybridization or hybridization induced by chemical means, temperature changes, or irradiation.

      The process of hybridization is important biologically because it increases the genetic variety (number of different gene combinations) within a species, which is necessary for evolution to occur. If climatic or habitat conditions change, individuals with certain combinations may be eliminated, but others with different combinations will survive. In this way, the appearance or behaviour of a species gradually may be altered. Such natural hybridization, which is widespread among certain species, makes the identification and enumeration of species very difficult.
