| 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 trait | An outstanding mental or physical characteristic. See: dominance of traits. (05 Mar 2000) |
| qualitative 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) |
| quantitative trait | A characteristic showing quantitative inheritance such as skin pigmentation in man. (12 Dec 1998) |
| intermediate trait | A measurable trait in which there is some evidence of the operation of a simple major cause, but in which the variation within the putative categories is such as to cause overlap and hence ambiguity in classification of any particular reading. (05 Mar 2000) |
| threshold trait | A trait that falls into natural groups that originate not in categorically distinct causes but in whether or not the outcome attains critical values; e.g., gallstones may result from a categorical cause or from unusual levels of causal factors that themselves show no evidence of grouping. Synonym: liminal trait. (05 Mar 2000) |
| trait | A qualitative characteristic; a discrete attribute as contrasted with metrical character. A trait is amenable to segregation rather than quantitative analysis; it is an attribute of phenotype, not of genotype. Origin: Fr. From L. Tractus, a drawing out, extension (05 Mar 2000) |
| liminal trait | A trait that falls into natural groups that originate not in categorically distinct causes but in whether or not the outcome attains critical values; e.g., gallstones may result from a categorical cause or from unusual levels of causal factors that themselves show no evidence of grouping. Synonym: liminal trait. (05 Mar 2000) |
| adhesion structures linked tyrosine kinase | <enzyme> Isolated from mouse embryonic stem cells Registry number: EC 2.7.1.- Synonym: hyk protein (26 Jun 1999) |
| benzylviologen-linked aldehyde oxidoreductase | <enzyme> A coenzyme a-independent tungsten-containing aldehyde oxidoreductase; from desulfovibrio gigas; n-terminal amino acid sequence given in first source Registry number: EC 1.2.7.- Synonym: bv-aldh (26 Jun 1999) |
| recessive, x-linked | A gene on the X chromosome that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, duchenne muscular dystrophy (dmd) is an x-linked recessive disorder. A dmd boy has the dmd gene on his sole x chromosome (and so is said to be hemizgous for dmd). Although it is much rarer, a girl can have dmd (by several different means as, for example, if she has the dmd gene on both her x chromosomes and so is homozygous for dmd). (12 Dec 1998) |
| x-linked | On the X chromosome. Linked in genetics does not mean merely associated. An x-linked gene travels with the x chromosome and therefore is part of the x chromosome. (12 Dec 1998) |
| X linked disease | <disease, genetics> A genetic or inherited disease whose controlling gene or at least part of the relevant genome is carried on an X chromosome, for example haemophilia. most known conditions are recessive and thus since males have only one X chromosome they will express any such recessive character. Few dominants are known and the homozygous states are very rare so that female expression of such diseases is uncommon. (18 Nov 1997) |
| X-linked gene | A gene located on an X chromosome. (05 Mar 2000) |
| X-linked hypogammaglobulinaemia | A congenital, X-linked recessive, primary immunodeficiency characterised by decreased numbers (or absence) of circulating B-lymphocytes with corresponding decrease in immunoglobulins of the five classes; associated with marked susceptibility to infection by pyogenic bacteria (notably, pneumococci and Haemophilus influenzae) beginning after loss of maternal antibodies. X-linked hypogammaglobulinaemia with growth hormone deficiency, hypogammaglobulinaemia combined with a reduced number of B-cells; characterised by short stature, delayed puberty, and recurrent infections.
