| discrete character | Classifiable character that is also countable (e.g., number of progeny, number of teeth). Synonym: discrete character. (05 Mar 2000) |

| dominant | <genetics> A gene is said to be dominant if it expresses its phenotype even in the presence of a recessive gene. (09 Oct 1997) |
| dominant eye | The eye that is customarily used for monocular tasks. Synonym: master eye. (05 Mar 2000) |
| dominant frequency | The frequency occurring most often in an electroencephalogram. (05 Mar 2000) |
| dominant gene | dominance of traits |
| dominant hemisphere | That cerebral hemisphere containing the representation of speech and controlling the arm and leg used preferentially in skilled movements; usually the left hemisphere. (05 Mar 2000) |
| dominant idea | An idea that governs all one's actions and thoughts. (05 Mar 2000) |
| 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) |
| inherited character | A single attribute of an animal or plant that is transmitted at one locus from generation to generation in accordance with Mendel's law. See: gene. Synonym: unit character. (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) |
| unit character | <genetics> A particular trait or characteristic (usually controlled by a single gene or a set of inseparable genes) that is passed on as a unit in heredity. (09 Oct 1997) |
