Problem set 2 key 1. Two islands in the Pacific are at Hardy-Weinberg equilibrium for blood types A, B and AB. No other blood types are found on these two islands. In the first island, the frequency of the I A allele is 0.3 and in the second it is 0.8. The two islands have the same number of people living on them. Due to global warming, one island is submerged under the ocean, and all the inhabitants move to the other island, which is hillier. a. What is the frequency of the I A allele immediately after all the inhabitants move? (0.3+0.8)/2=0.55 b. If none of the assumptions of Hardy-Weinberg are violated, how many generations will it take before Hardy-Weinberg equilibrium is reached? 1 c. After a sufficient number of generations, you test the blood-types of 100 individuals. 36 have blood-type A, 38 have blood type AB and 26 have blood type B. Have the allele frequencies changed from your answer to part a? The allele frequencies are p=freq(I
