| 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) |
| airspace-filling pattern | Cloudy to dense opacities, obscuring vascular markings, on chest radiographs. Synonym: airspace-filling pattern. (05 Mar 2000) |
| airway pattern | Chest radiographic appearance of thickened bronchial walls, bronchiectasis, bronchiolitis, or acinar consolidation. (05 Mar 2000) |
| alveolar pattern | Cloudy to dense opacities, obscuring vascular markings, on chest radiographs. Synonym: airspace-filling pattern. (05 Mar 2000) |
| A-pattern strabismus | Strabismus in which esotropia is more marked in looking upward than downward, strabismus in which exotropia is more marked on looking downward than upward. Synonym: A-pattern strabismus. (05 Mar 2000) |
| axial pattern flap | A flap that includes a direct specific artery within its longitudinal axis. Synonym: arterial flap. (05 Mar 2000) |
| ballerina-foot pattern | A vigorous posteromedial contraction of the left ventricle coupled with convexity anteriorly sometimes resulting from poor contraction of the opposing anterior wall; it is the most frequent dyssynergy observed in the prolapsed mitral valve leaflet syndrome (even with a normal anterior wall) and produces a configuration of angiographic dye in the right anterior oblique projection resembling a ballerina's foot; sometimes called dancer's foot malformation. (05 Mar 2000) |
| banding pattern | <genetics> Chromosomes stained with certain dyes, commonly quinacrine (Q banding) or Giemsa (G banding), show a pattern of transverse bands of light and heavy staining that is characteristic for the individual chromosome. The basis of the differential staining, which is the same in most tissues, is not understood: each band represents 5-10% of the length, about 10exp7 base pairs, although this is not true for polytene chromosomes in Drosophila that show more than 4000 bands. (18 Nov 1997) |
| butterfly pattern | Bilateral, symmetric, pulmonary alveolar opacities sparing the periphery, on chest radiographs; usually caused by pulmonary oedema. (05 Mar 2000) |
| male pattern alopecia | The most common form of androgenic alopecia, seen in men as receding frontal and bilateral triangular temple hair lines, and a balding patch on the vertex, which may progress to complete alopecia. Synonym: male pattern baldness. (05 Mar 2000) |
| male pattern baldness | The most common form of androgenic alopecia, seen in men as receding frontal and bilateral triangular temple hair lines, and a balding patch on the vertex, which may progress to complete alopecia. Synonym: male pattern baldness. (05 Mar 2000) |
