As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Suppose that, in a large population at equilibrium, the frequency of the IA allele is 0.35 and the frequency of the IB allele is 0.15.

a. What is the expected frequency of people with type AB blood in this population?
b. What is the expected frequency of people with type A blood?
c. A blood bank collects 5000 pints of blood during a blood drive and finds that 1850 were type A, 635 were type B, 180 were type AB and 2335 were type O. Calculate the frequencies of the IA ,IB, and i alleles in this population. (Hint: you should first determine the iallele frequency. Then you can use the quadratic equation to solve for IAand then solve for IB)
