In a classroom taste test for PTC the genotype frequency was determined to be P = 0.35 and Q = 0.65.After applying the Hardy-Weinberg equation, the percentage of genotypes was found to be as follows:

According to the Hardy-Weinberg equation, p2 + 2pq + q2 = 1. Using the given frequencies, we can solve for each genotype frequency as follows:
p2 = P x P = 0.35 x 0.35 = 0.1225
2pq = 2 x P x Q = 2 x 0.35 x 0.65 = 0.455
q2 = Q x Q = 0.65 x 0.65 = 0.4225
Rounding to two decimal places, we get the genotype frequencies of p2 = 0.12, 2pq = 0.46, and q2 = 0.42. Therefore, the best choice is B.
