AP Biology· difficulty 2/5
A population of 100 individuals is genotyped at one locus. The table shows observed genotype frequencies.
What is the frequency of the dominant allele A in this population?
0.4
0.6
0.36
0.84
Explanation
p = freq(AA) + (1/2)freq(Aa) = 0.36 + 0.24 = 0.60. Therefore the A allele frequency is 0.6.

In a large randomly mating population, allele a is recessive lethal — homozygotes aa die before reproducing. Currently q = 0.2. Assuming no other forces, what i…
