The actual number of squirrels in this population that had brown-black fur was 16. Use all of the information to calculate the actual frequency of the CG allele. Do not use the Hardy–Weinberg equation in your calculation.

16 x 2 + 16 x 1 / 34 x 2 = 0.71

Total Grey number= 34-16-2=16, so it have 32 G allele
Total brown-black fur=16, so it have 16 G & 16B allele
Total G allele is 32+16=48
48/68(total population allele)=0.705,=0.71
