Genetics Biology Problem?

Yes, the closest answer is (d). Freckles are caused by a dominant allele, F. If the frequency of "no freckles" is 0.19, then the frequency of ff is 0.19 and the frequency of f is sqrt(0.19) = 0.4359. Therefore, the frequency of F is 1 - 0.4359 = 0.5641, and the frequency of FF is (0.5641)↑2 = 0.3182.
