| paraplegia in extension | Paralysis of the legs, maintained in an extended position by hypertonic extensor muscles. (05 Mar 2000) |
|---|---|
| paraplegia in flexion | The fixation of the paralysed legs in a flexed posture; usually in transection of the spinal cord. (05 Mar 2000) |
| Pott's paraplegia | Paralysis of the lower part of the body and the extremities, due to pressure on the spinal cord as the result of tuberculous spondylitis. Synonym: Pott's paralysis. (05 Mar 2000) |
| superior paraplegia | Paralysis of both arms. (05 Mar 2000) |
| genes, dominant | Genes that are reflected in the phenotype both in the homozygous and the heterozygous state. (12 Dec 1998) |
| permanent dominant idea | An exaggerated notion, belief, or delusion that persists, despite evidence to the contrary, and controls the mind, the obstinate conviction of a psychotic person regarding the correctness of his delusion. Synonym: idee fixe, overvalued idea, permanent dominant idea. (05 Mar 2000) |
| dominant | <genetics> A gene is said to be dominant if it expresses its phenotype even in the presence of a recessive gene. (09 Oct 1997) |
| dominant character | An inherited character determined by one kind of allele. See: phenotype. (05 Mar 2000) |
| dominant eye | The eye that is customarily used for monocular tasks. Synonym: master eye. (05 Mar 2000) |
| dominant frequency | The frequency occurring most often in an electroencephalogram. (05 Mar 2000) |
| dominant gene | dominance of traits |
| 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 inheritance | dominance of traits |
| 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) |
