DNA typing is used to compare evidence DNA (E) left at a crime scene to two suspects (S1 and S2). Suspect 1 is excluded by the evidence, but suspect 2 remains included. What is the frequency of suspect 2's genotype if the allelic frequencies in the population are f(A₁) = 0.1, f(A₂) = 0.2, and f(A₃) = 0.7, and the population is at Hardy-Weinberg equilibrium?
