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.
