| 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).

|---|---|
| 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) |
| absorptive cells of intestine | Cell's on the surface of villi of the small intestine and the luminal surface of the large intestine that are characterised by having microvilli on their free surface. (05 Mar 2000) |
| air cells | Air-containing spaces in the skull. See: pulmonary alveolus. (05 Mar 2000) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| Alpha cells | Alpha cell's of pancreas or of anterior lobe of hypophysis. (05 Mar 2000) |
| alpha cells of anterior lobe of hypophysis | Acidophil cell's that constitute about 35% of the cell's of the anterior lobe. There are two varieties: one that elaborates somatotropin, another that elaborates prolactin. (05 Mar 2000) |
| alpha cells of pancreas | Cell's of the islets of Langerhans that secrete glucagon. (05 Mar 2000) |
