hybrid

(1) More than one. Hybrid implies at least two modes, styles or processes.

(2) Products that combine two or more different technologies. For data and software hybrids, see hybrid file, hybrid app and hybrid mobile app. For hardware hybrids, see hybrid laptop, hybrid computer, hybrid cloud, eSATA USB Hybrid Port, hybrid smartwatch, hybrid drive, hybrid circuit and hybrid microcircuit.

(3) Also known as a "termination" or "term set," a hybrid is a device that adapts a two-wire telephone line from a home or business into a four-wire trunk at the telco central office. Hybrids also exist within the telephone handset, converting the two-wire line into four wires: two for the speaker; two for the microphone. See echo cancellation.

Hybrid

 

sexual offspring produced by the crossing of two genotypically different organisms. The organisms crossed are called parental forms and are designated by the letter P. The maternal form or female individual is designated by the symbol ♀ , the paternal form or male individual by the symbol ♂, crossing by the symbol ×, hybrid offspring of the first generation by F with the subscript 1 (F1), second generation by F2, and so forth. For example, the F4 hybrid of ♀(beardless wheat) Bezostaia 1 × ♂ Belotserkovskaia 198 is the fourth generation of the hybrid in which the maternal form was Bezostaia 1 and the paternal form Belotserkovskaia 198. Hybrids may be spontaneous or artificial, intraspecific or remote. The following hybrids are distinguished in breeding corn: the intervarietal, when two varieties are crossed; the variety-line hybrid, when a variety is crossed with an inbred line (for example, to produce the hybrid Bukovinskii 3: ♀ Gloriia lanetskogo × ♂ VIR 44); the single cross hybrid, from the crossing of two strains (for example, the hybrid Slava is produced by crossing the inbred lines ♀ VIR 44 ×♂ VIR 38); and the double cross hybrid from crossing two simple hybrids (for example, the hybrid VIR 42 is produced by crossing ♀ Slava × ♂ Svetoch).

Biological anthropologist Rebecca Ackermann of the University of Cape Town in South Africa co-organized the session to introduce researchers steeped in human evolution to the ins and outs of hybridization in animals and its potential for helping to identify signs of interbreeding on fossils typically regarded as either H.
Other Melanesian genetic sequences acquired through ancient interbreeding either include or adjoin genes that help to marshal the body's defenses against illness.
By occasionally interbreeding with Neandertals after leaving Africa around 70,000 years ago, Stone Age humans inherited and retained keratin-related genes that must have aided survival outside of Africa, Sriram Sankararaman, a computational geneticist at Harvard Medical School, and his colleagues propose January 29 in Nature.

Some suspect there was even more Stone Age interbreeding than these numbers suggest, shaping the genetic evolution of H.
Other studies have found that ancient interbreeding may not be necessary to explain the presence of Neandertal DNA in modern humans.
Using projected rates of genetic mutation and data from the fossil record, the researchers suggest that the interbreeding happened about 60,000 years ago in the eastern Mediterranean and, more recently, about 45,000 years ago in eastern Asia.
The evidence for past interbreeding is convincing, says Richard "Ed" Green, a genome biologist at the University of California, Santa Cruz.
Since Neanderthals lived side by side with modern humans in Europe for many thousands of years, it has been speculated that we may have inherited some Neanderthal DNA in our genome today, thanks to interbreeding.
"The question is no longer 'When did ancient populations such as Neandertals go extinct?' but 'What happened to those populations and to modern humans as a result of interbreeding?'" says anthropologist John Hawks of the University of Wisconsin-Madison.
