| dominant inheritance | dominance of traits |
|---|---|
| dominant lethal trait | Trait, expressed in the phenotype if present in the genotype, that precludes having descendants. All such cases are necessarily sporadic and must represent new mutations as the usual methods of classical genetics provide no means of demonstrating any genetic component whatsoever, except for tenuous arguments such as advanced paternal age. Molecular biology may help although the methods may be tedious; if there is an epistatic gene that may mask the trait, the logic is more tractable, though complex. (05 Mar 2000) |
| dominant oncogene | <genetics, molecular biology, oncology> A gene that stimulates cell proliferation and can drastically increase the risk of cancer development when present in a single copy. (09 Oct 1997) |
| dominant species | <biology, ecology, zoology> For each stratum, dominant species are those that, when ranked in descending rank order and cumulatively totaled, immediately exceed 50 percent of the total dominance measure, plus any additional species comprising 20 percent or more of the total dominance measure for the stratum. (09 Oct 1997) |
| dominant trait | An outstanding mental or physical characteristic. See: dominance of traits. (05 Mar 2000) |
| kidney, polycystic, autosomal dominant | A genetic disorder with autosomal dominant inheritance characterised by multiple cysts in both kidneys and progressive deterioration of renal function. It is usually caused by a mutant gene at the pkd1 locus on the short arm of chromosome 16, though mutations elsewhere in the genome can also cause the disease. The age of onset of symptoms varies widely. (12 Dec 1998) |
| age-related macular degeneration | A common macular degeneration beginning with drusen of the macula and pigment disruption and sometimes leading to severe loss of central vision. (05 Mar 2000) |
| macular | Maculate 1. Relating to or marked by macules. 2. Denoting the central retina, especially the macula retinae. (05 Mar 2000) |
| macular amyloidosis | A localised form of amyloidosis cutis characterised by pruritic symmetrical brown reticulated macules, especially on the upper back; microscopically, amyloid is deposited as small subepidermal globules. (05 Mar 2000) |
| macular area | An oval area of the sensory retina, 3 by 5 mm, temporal to the optic disk corresponding to the posterior pole of the eye; at its centre is the central fovea, which contains only retinal cones. Synonym: area centralis, macula lutea, macular area, punctum luteum, Soemmerring's spot, yellow spot. (05 Mar 2000) |
| macular arteries | See: inferior macular arteriole, superior macular arteriole. (05 Mar 2000) |
| macular atrophy | Atrophoderma in which the skin becomes bag like and wrinkled. Synonym: atrophia maculosa varioliformis cutis, atrophoderma maculatum, macular atrophy, primary idiopathic macular atrophy, primary macular atrophy of skin. Origin: G. Anetos, relaxed, + derma, skin (05 Mar 2000) |
| macular coloboma | A defect of the central retina as a result of arrested development or intrauterine retinal inflammation. (05 Mar 2000) |
| macular degeneration | <ophthalmology> Breakdown or damage to a portion of the retina known as the macula. Symptoms include blurring of vision (in central visual field), colours appear dim and difficulty reading or performing work up close. (27 Sep 1997) |
| macular drusen | Excrescences of Bruch's membrane that produce a window in the retinal pigment epithelium and are a feature of age-related macular retinal degeneration. Synonym: macular drusen. (05 Mar 2000) |
