| 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) |
| alteration | 1. A change. 2. A changing; a making different. (05 Mar 2000) |
| modal alteration | In electric irritability, a change in the mode of response of degenerated muscle to electric stimulation, the contraction being sluggish instead of quick. (05 Mar 2000) |
| quantitative alteration | In electric irritability, a gradual loss of contractility in a muscle in response to static, faradic, and galvanic currents successively. (05 Mar 2000) |
