Calculate the frequency of the genotypes using Hardy-Weinberg?

The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele t are unable to taste this compound. In a group of 125 people there are 88 students able to taste PTC and 37 who could not. Calculate the frequency of the genotypes.

    Since 37/125 could not taste PTC, fr(tt) must be 37/125 = 0.2960. Therefore, fr(t) = sqrt(0.2960) = 0.5441 you can call q, and fr(T) = 1-0.5441 = 0.4559, you can call p.

    Fr(TT) = p↑2 = 0.2078

    Fr(Tt) = 2pq = 0.4961

    Fr(tt) = q↑2 = 0.2960
