Detailed explanation-1: -In the equation, p2 represents the frequency of the homozygous genotype AA, q2 represents the frequency of the homozygous genotype aa, and 2pq represents the frequency of the heterozygous genotype Aa. In addition, the sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.
Detailed explanation-2: - 2pq = the frequency of the heterozygous dominant genotype. p2 = the frequency of homozygous dominant genotype.
Detailed explanation-3: -So, the correct answer is ‘2pq’
Detailed explanation-4: -For values of p from 0 to 1, in intervals of 0.1, here’s what we get: p+q=1, so p=1-q and q=1-p. Red represents the frequency of the AA or A1A1 genotype, green is the Aa or A1A2 genotype, and blue is the aa or A2A2 genotype. All of the above has to do with the allele and genotype frequencies we would expect to see.
