genotype frequency

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

genotype frequency

the proportion of a particular genotype amongst all the individuals in a population. Thus, if a population sample contained 5 albinos and 95 normally-pigmented individuals, the genotype frequency of albinos (a/a) would be 0.05 or 5%. Note, however, that it is not possible to be certain of the frequency of A/a and A/A genotypes among the normal individuals, since both genotypes have the same PHENOTYPE due to dominance, although their frequencies can be predicted using the HARDY-WEINBERG LAW.


1. the entire genetic constitution of an individual; also, the alleles present at one or more specific loci.
2. the type species of a genus.

genotype frequency
the proportion of the population which have the same genetic constitution.
