You have sampled a population in which you know that the percentage of the homozygous dominant genotype (AA) is 16%.
Using that 16%, calculate the following - the frequency of the "A" allele. (p)
p2 + 2pq + q2 = 1 and p + q = 1
a
1
b
0.4
c
0.16
d
0.36
c) 0.16
Since the percentage of the homozygous dominant genotype (AA) is 16%, the frequency of the "A" allele would be the square root of 0.16, which is 0.4.
