| 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 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) |
| alternative inheritance | Galton's term for an assumed form in which all the characters are derived from one parent. (05 Mar 2000) |
| blending inheritance | Galton's term for inheritance in which no component is conspicuous or obtrusive. (05 Mar 2000) |
| galtonian inheritance | Inheritance in which a measurable phenotype is generated by many loci, the contributions of which are statistically independent, additive, and of about equal value. (The latter are in accordance with the classical central limit therein and justify the use of the multivariate normal distribution in galtonian genetics). Synonym: polygenic inheritance. (05 Mar 2000) |
| recessive inheritance | dominance of traits |
| maternal inheritance | Inheritance through the maternal cell line, for example through the oocyte and eggs. Mitochondrial genes are maternally inherited and various other nonMendelian forms of inheritance may also appear as maternal inheritance. (18 Nov 1997) |
| Mendelian inheritance | <genetics> Inheritance of characters according to the classical laws formulated by Gregor Mendel, which give the classic ratios of segregation in the F2 generation. In sexually reproducing organisms, any process of heredity explicable in terms of chromosomal segregation, independent assortment and homologous exchange. (18 Nov 1997) |
| Mendelian Inheritance in Man | A standard, comprehensive, perpetually updated reference source for traits in humans that have been shown to be mendelian or that are thought on reasonable grounds to be so. Each entry has a six-digit catalog number. Those securely established (by molecular biology or by extensive clinical studies) are marked with an asterisk. (05 Mar 2000) |
| mitochondrial inheritance | The inheritance of a trait encoded in the mitochondrial genome. Because of the oddities of mitochondria, mitochondrial inheritance does not obey the classic rules of genetics. Persons with a mitochondrial disease may be male or female but they are always related in the maternal line and no male with the disease can transmit it to his children. (12 Dec 1998) |
| codominant inheritance | Inheritance in which two alleles are individually expressed in the presence of each other; there may be other alleles available at the locus that may or may not exhibit codominance. (05 Mar 2000) |
