the hardy-weinberg equation is as follows:

where is homozygous dominant, 2pq is heterozygous, and is recessive.

we also know that:

so then we can solve for q:

so then we can solve for the heterozygous term:

so now we know that the percentage of the population that should be heterozygous is 39.6%.
