Detailed explanation-1: -Therefore, the frequency of the dominant phenotype equals the sum of the frequencies of AA and Aa, and the recessive phenotype is simply the frequency of aa. Therefore, the dominant frequency is 64% and, in the first part of this question above, you have already shown that the recessive frequency is 36%.

Detailed explanation-2: -According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency. The dominant allele frequency is 0.7.

Detailed explanation-3: -Hardy Weinberg equation says, p2+2pq+q2=1, where q2 is the frequency of homozygous recessive gene.
