dictionary help| skipped generation | medical dictionary |
A phenomenon of pedigrees in which a gene is transmitted from one affected person to another through a phenotypically unaffected person, as by recessivity (especially for X-linked traits), epistasis, variable expressivity, or absence of an environmental challenge such as a toxin. Except at a crass phenotypic level (e.g., clinical or commercial) this term becomes progressively less useful as the mechanisms are elucidated.
