| 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 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) |
| Bombay trait | A rare recessive trait at a locus that ordinarily manufactures H substance, the precursor from which the A and B phenotypes are elaborated; the mutant causes failure to produce H substance and no matter what the genotype at the ABO locus, the phenotype is O. The Bombay phenomenon is epistatic to the ABO locus. Origin: Bombay, India, where first reported (05 Mar 2000) |
| galtonian trait | A quantitative genetic trait due to contributions from many more of less equally important loci that resembles a continuous trait. (05 Mar 2000) |
| recessive trait | See: dominance of traits. (05 Mar 2000) |
| marker trait | A trait that may be of little importance in itself but which by association, linkage, or other means facilitates the detection, anticipation, or understanding of a disease or (for genetic diseases) the localization of the causative gene on the karyotype. (05 Mar 2000) |
| categorical trait | <genetics> A feature that can conveniently and effectively be analyzed by sorting into classes either because there is no satisfactory way of measuring it (as with blood groups) or because it falls into natural classes so that the variation among classes far exceeds that within classes (e.g., the phenotypic effects of many enzyme polymorphisms); existence of categories suggests but does not prove the operation of a major, simple, underlying cause. Synonym: qualitative trait. (05 Mar 2000) |
| penetrant trait | A trait that in the appropriate genotypes is phenotypically manifest; strictly, it is the trait that is penetrant, not the gene. See: penetrance. (05 Mar 2000) |
| mendelian trait | A categorical trait that segregates in accordance with a single-locus genetic system. (05 Mar 2000) |
| chromosomal trait | A trait dependent on a recurrent chromosomal aberration. (05 Mar 2000) |
| codominant trait | See: codominant. (05 Mar 2000) |
