| silent allele | 1. <genetics> A gene which is inactive. Thus, an amorphic gene. 2. <cell biology> Something that lacks a discernible shape and thus can be describes as amorphous. (05 Feb 1998) |

| allele | <genetics> Any one of a series of two or more different genes that occupy the same position (locus) on a chromosome. Since autosomal chromosomes are paired, each autosomal locus is represented twice. If both chromosomes have the same allele, occupying the same locus, the condition is referred to as homozygous for this allele. If the alleles at the two loci are different, the individual or cell is referred to as heterozygous for both alleles. (15 Nov 1997) |
|---|---|
| amorphic allele | <genetics, molecular biology> An allele which is genetically inactive. (05 Feb 1998) |
| codominant allele | In genetics, denoting an equal degree of dominance of two genes, both being expressed in the phenotype of the individual; e.g., genes A and B of the ABO blood group are codominant; individuals with both are type AB. (05 Mar 2000) |
| masticatory silent period | A pause in electromyographic patterns associated with tooth contacts during chewing and biting; a part of the complex feedback mechanism of mandibular control involving receptors in the periodontal ligament and muscles. (05 Mar 2000) |
| silent | Producing no detectable signs or symptoms, said of certain diseases or morbid processes. (05 Mar 2000) |
| silent area | Any area of the cerebrum or cerebellum in which lesions cause no definite sensory or motor symptoms. (05 Mar 2000) |
| silent electrode | In unipolar electrocardiography, a remote electrode placed either upon a single limb or connected with the central terminal and paired with an exploring electrode; the indifferent electrode is supposed to contribute little or nothing to the resulting record. Synonym: dispersing electrode, silent electrode. (05 Mar 2000) |
| silent gap | The period during which Korotkoff sounds indicating true systolic pressure fade away and reappear at a lower pressure point; responsible for errors made in recording falsely low systolic blood pressure, especially in hypertensive patients, of up to 25 mm Hg, and avoided by pumping the cuff 30 mm Hg beyond palpable systolic pressure. Synonym: silent gap. (05 Mar 2000) |
| silent ischemia | Myocardial ischemia without accompanying signs or symptoms of angina pectoris; can be detected by EKG and other lab techniques. See: silent myocardial infarction. (05 Mar 2000) |
| silent mutant | A mutant that is not phenotypically manifest. Synonym: silent mutant. (05 Mar 2000) |
| silent mutation | Mutations that have no effect on phenotype because they do not affect the activity of the product of the gene, usually because of codon ambiguity. (18 Nov 1997) |
| silent myocardial infarction | Infarction that produces none of the characteristic symptoms and signs of myocardial infarction. (05 Mar 2000) |
| silent period | The time during which there is no electrical activity in a muscle following its rapid unloading, any pause in an otherwise continuous series of electrophysiologic events. (05 Mar 2000) |
