1 | Page Genetic Analysis II (385) Professor Gordon 03/30/2011 Recitation03 Name_____________________________ 1. For the given two-locus gamete frequencies in Examples 01, 02 below, compute: (i) the disequilibrium value D using the observed frequencies; and (ii) determine whether the two loci are jointly in Hardy-Weinberg Equilibrium or not. Assume that the recombination fraction between the two loci is 0.5 (completely unlinked). Place your answers in Table 01. Table 01. Observed two-locus gamete frequencies. Example f(AB) f(Ab) f(aB) f(ab) D(0) In Equilibrium? 01 0.40 0.05 0.30 0.25 02 0.50 0.20 0.20 0.10 2. A group of 4000 Blackpool Night-sifters (2500 male, 1500 female) have the following genotype counts at the SuperTrifecta locus: a.
