The frequency of genotype Aa can be determined using the equation: 
frequency of Aa = 2 * square root of (frequency of AA * frequency of aa)
First, we need to calculate the frequency of aa by subtracting the frequency of AA from 1: 
frequency of aa = 1 - 0.36 = 0.64 
Now we can plug in the values: 
frequency of Aa = 2 * square root of (0.36 * 0.64) = 0.48 
Therefore, the frequency of Aa is 0.48.
