Human blood type is determined by three alleles I^A, I^B, and I^O. The alleles I^A and I^B are co-dominant to each other, and both are dominant to I^O. Within a large, randomly mating population (540,000 individuals), the frequencies for the blood type alleles are 0.3 for the I^A allele, 0.6 for the I^Oallele, and 0.1 for the I^B allele.
a. Calculate the expected numbers of people in the population having each of the blood types A, B, AB, and O.
b. Determine the percentage of type B people that are heterozygotes (I^BI^O).
