Using the Hardy Weinberg principle, calculate the frequency of the heterozygous genotype in the population if the frequency of the dominant allele p is 0.864. Express your answer as a percentage of the population.

p2 + 2pq + q2 = 1.0
p + q = 1.0
1.0 - p = q
1.0 - 0.864 = 0.136
q = 0.136
Frequency of heterozygous genotype = 2pq
2 x 0.864 x 0.136 = 0.235
As a percentage of the population- 23.5%
