| 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) |
| 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) |
| acute lower GI haemorrhage | <gastroenterology> Typical presentation: Sudden onset of brisk rectal bleeding without blood in gastric aspirate Diagnostic considerations: diverticulosis, angiodysplasia, ischemic colitis, inflammatory bowel disease (rarely), polyps are usually present, carcinoma causing a chronic bleed, haemorrhoids.

| anterior surface of lower limb | The anterior surface of the inferior limb. Synonym: facies anterior membri inferioris. (05 Mar 2000) |
| arterial arch of lower eyelid | Formed by the medial palpebral artery which communicates with a branch of the lacrimal artery along the tarsal margin. Synonym: arcus palpebralis inferior. (05 Mar 2000) |
| bones of lower limb | These include the inferior limb girdle (hip bone) and the skeleton of the free inferior limb (femur, tibia, fibula, patella, tarsus, metatarsus, and bones of the toes). Synonym: ossa membri inferioris, bones of inferior limb. (05 Mar 2000) |
| regions of lower limb | The topographic divisions of the lower limb: gluteal, thigh (or femoral), knee, leg (or crural), ankle, and foot. Synonym: regiones membri inferioris, regions of inferior limb. (05 Mar 2000) |
| mean lower low water | <marine biology> The average height of the lower low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |
