How do you calculate heterozygous?

To calculate heterozygosity in a population, you first need to determine the frequency of the alleles at a specific locus. If you have two alleles, A and a, the heterozygosity (H) can be calculated using the formula: H = 2pq, where p is the frequency of allele A and q is the frequency of allele a (with p + q = 1). Heterozygosity represents the proportion of individuals in a population that are heterozygous for that locus. This measure is useful for understanding genetic diversity within a population.
