Question 3 Not yet answered Points out of 1.0 Kermode bears (Ursus americanus kermodei) are white bears that can be found in the rainforest on Princess Royal and Gribbell islands along the coast of British Columbia. This subspecies of black bears is known as the Spirit Bear. Its white fur is the result of a single nucleotide replacement in the melanocortin-1 (Mc1r) receptor portion of that gene that leads to the production of adenine instead of guanine. The white fur allele is a recessive allele unique to this subspecies. Dr. Kermit Ritland and his colleagues found that approximately 20 percent of the bears on Princess Royal and Gribbell islands are white; the rest are black. The percentage of white bears on the mainland drops off drastically with distance from those islands. Flag question Assuming complete dominance, calculate the expected genotype frequencies: q equals p equals 2pq equals Question 4 Based on Q3 above, for a randomly mating population at equilibrium, the Hardy-Weinberg theorem gives us the genotype frequencies expected for Kermode bears: Points out of 1.0 Flag question BB genotypes should occur at a frequency of BW genotypes should occur at a frequencyV and ww genotypes should occur at a freque 55% 67% 31% 25% 20% 49% Question 5 Based on Q3, above, if you had a populati°r on the two islands, you would expect that
