heterozygosity The presence of different alleles (forms of a given gene) at a particular gene locus. Heterozygosity provides a measure of the genetic variation, either in a population (the frequency of individuals heterozygous at a particular locus), or in an individual (the proportion of gene loci that are heterozygous).
