gene frequency


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

gene fre·quen·cy

1. the probability that a gene picked at random from a defined population is of a particular type;
2. epidemiologically, the proportion of genes in a population that are of the particular type;
3. statistically, the estimate of either of the foregoing two quantities.

allele frequency

A term used in population genetics for the number of copies of a particular allele divided by the number of copies of all alleles at that specific genetic locus in a population of interest. Allele frequency is a measure of a population’s genetic diversity: the higher the allele frequency, the greater the population’s consanguinity.
