c. Biology. Designating genetic material or a gene considered primarily as an element which tends to replicate itself through successive generations of a population, or within a genome, any effect on the organism being derivative of this tendency. Earliest and chiefly in selfish gene.In quot. 1964: designating genes for characteristics conferring benefits on particular individuals, in the context of competition within a species.The theory of the selfish gene developed by Richard Dawkins (b. 1941), British scientist and writer (cf. quot. 1976), aims to understand the evolution of organisms in terms of the gene as replicator. In genetics, the term is applied chiefly to genetic material which is perpetuated in the genome despite having no phenotypic effect.
