| hybrid inviability | <biology> The observation that certain hybrid organisms have lower fitness than the parent organisms, for example they grow more poorly or have lower survival rates. Hybrid inviability is the opposite of hybrid vigor. (09 Oct 1997) |
|---|---|
| hybrid molecule | <molecular biology> A double-stranded nucleic acid molecule which was artificially created from two different single-stranded nucleic acid molecules from different sources, for the purpose of comparing their nucleotide sequences. (09 Oct 1997) |
| hybrid name | <zoology> Names given to hybrids are not normally available, as they are individuals, not populations, and hence not taxa. (09 Jan 1998) |
| hybrid plasmid | <molecular biology> A plasmid (circular DNA molecule) which is composed partly of the DNA of an organisms (or virus's) genome and partly of foreign DNA that has been inserted artificially. (09 Oct 1997) |
| hybrid prosthesis | A complete denture that is supported by both soft tissue and natural teeth that have been altered so as to permit the denture to fit over them. The altered teeth may have been fitted with short or long copings, locking devices, or connecting bars. Synonym: bar joint denture, hybrid prosthesis, overdenture, telescopic denture. (05 Mar 2000) |
| hybrid resonance | <radiobiology> A resonance in a magnetised plasma which involves aspects of both bunching of lighter species parallel to the magnetic field, characterised by the plasma frequency, and perpendicular particle motions (heavier species) characterised by the cyclotron frequency. (09 Oct 1997) |
| hybrid sterility | <genetics, zoology> The inability of a hybrid to produce viable offspring. Whether an animal hybrid is sterile or fertile depends mainly on how closely its two parent species are related. For example: mules (which are hybrids between male donkeys and female horses) are usually sterile, while hybrids between domestic dogs and wolves are fertile (hybrids between wolves and foxes are also fertile, but hybrids between dogs and foxes are sterile). (09 Oct 1997) |
| hybrid swarm | A group of morphologically distinctive individuals which results from the creation of hybrids between two parent species, then the backcrossing of the offspring to members of the parent species and the interbreeding among the hybrid individuals. (09 Oct 1997) |
| hybrid vigor | The adaptive superiority of heterozygous genotypes with respect to one or more characters in comparison with the corresponding homozygotes. (12 Dec 1998) |
| somatic hybrid | Heterokaryon formed between two somatic cells, usually from different species. See: somatic cell genetics. (18 Nov 1997) |
| SV40-adenovirus hybrid | A virion consisting of SV40 genetic material encased in an adenovirus capsid. (05 Mar 2000) |
| DNA-RNA hybrid | Double-stranded polynucleic acids in which one strand is DNA and the other strand is the complementary RNA; formed during transcription and during multiplication of oncogenic RNA viruses. (05 Mar 2000) |
| upper hybrid waves | <radiobiology> Similar to lower hybrid waves, but at a higher frequency. Not truly propagating waves, but plasma oscillations. (09 Oct 1997) |
| fusion-fission hybrid | <radiobiology> Proposed nuclear reactor relying on both fusion and fission reactions. A central fusion chamber would produce neutrons to induce fission in a surrounding blanket of fissionable material. The neutron source could also be used to convert other materials into additional fissile fuels (breeder hybrid). Safer than a plain fission reactor because the fission fuel relies on the fusion neutrons, and therefore cannot achieve criticality. On the other hand, hybrids are more complex because of the fusion power core, and still generate fission's radioactive byproducts. But a fusion-fission hybrid could be more economical and have less stringent technical requirements than a pure fusion reactor. (05 Jan 1998) |
| lower hybrid waves | <physics> Electrostatic ion oscillations at a frequency intermediate to the electron extraordinary wave (high frequency) and the magnetosonic wave (low frequency). (09 Oct 1997) |
