0.04
|

|
0.32
|
|
|
0.64
|
|
|
0.2

Explanation:
Detailed explanation-1: -So, the correct answer is ‘0.64’
Detailed explanation-2: -The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32).
Detailed explanation-3: -We know that the frequency of the recessive homozygote genotype is q2 and equal to 0.09.
Detailed explanation-4: -To find the allele frequencies, we again look at each individual’s genotype, count the number of copies of each allele, and divide by the total number of gene copies.
