To calculate genotypic frequencies, we need to divide the number of individuals with each genotype by the total number of individuals in the population. 
So, the total number of individuals in the population is 200 (60+120+20). 
The frequency of AA individuals is 60/200 = 0.30, Aa individuals is 120/200 = 0.60, and aa individuals is 20/200 = 0.10. 
Therefore, the genotypic frequencies in the population are 30% AA, 60% Aa, and 10% aa.
