Hey clergy, good to see you again. To calculate r^2 for the given haplotype frequencies, we need to follow these steps: Step 1: Determine the individual allele frequencies. Let the two loci have alleles A/a and B/b. From the table: Haplotype AB frequency (P_AB) = 0.15 Haplotype Ab frequency (P_Ab) = 0.35 Haplotype aB frequency (P_aB) = 0.25 Haplotype ab frequency (P_ab) = 0.25 Calculate the allele frequencies: Frequency of allele A (P_A) = P_AB + P_Ab = 0.15 + 0.35 = 0.50 Frequency of allele a (P_a) = P_aB + P_ab = 0.25 + 0.25 = 0.50 Frequency of allele B (P_B) = P_AB + P_aB = 0.15 + 0.25 = 0.40 Frequency of allele b (P_b) = P_Ab + P_ab = 0.35 + 0.25 = 0.60 Step 2: Calculate the D statistic (coefficient of linkage disequilibrium). The formula for D is D = P_AB - P_A P_B. Substitute the values: D = 0.15 - (0.50 × 0.40) D = 0.15 - 0.20 D = -0.05 Step 3: Calculate the r^2 statistic. The formula for r^2 is r^2 = (D^2)/(P_A P_a P_B P_b). Substitute the calculated values: r^2 = ((-0.05)^2)/((0.50)(0.50)(0.40)(0.60)) r^2 = (0.0025)/((0.25)(0.24)) r^2 = (0.0025)/(0.06) r^2 ≈ 0.041666... Rounding to four decimal places: r^2 ≈ 0.0417 The final answer is r^2 ≈ 0.0417.
