| gene expression regulation | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action at the level of transcription or translation. These processes include gene activation and genetic induction. (12 Dec 1998) |

| gene families | Groups of closely related genes that makesimilar products. (09 Oct 1997) |
| gene family | <molecular biology> A set of genes coding for diverse proteins which, by virtue of their high degree of sequence similarity, are believed to have evolved from a single ancestral gene. An example is the immunoglobulin family where the characteristic features of the constant domains are found in various cell surface receptors. (18 Nov 1997) |
| gene flow | The movement of genes from one population to another viainterbreeding. (09 Oct 1997) |
| gene frequency | The relative occurence (expressed as a percentage) of a gene in a given population. (09 Oct 1997) |
| gene fusion | Fusion of structural genes to analyze protein behaviour or fusion of regulatory sequences with structural genes to determine mechanisms of regulation. (12 Dec 1998) |
