Question 6

(Multiple Choice)

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


A) A = 243,000 people, B = 70,200 people, AB = 32,400 people, and O = 194,400 people
B) A = 162,000 people, B = 54,000 people, AB = 3,240 people, and O = 324,000 people
C) A = 48,600 people, B = 5,400 people, AB = 32,400 people, and O = 194,400 people
D) A = 194,400 people, B = 64,800 people, AB = 32,400 people, and O = 194,400 people
E) A = 243,000 people, B = 5,400 people, AB = 32,400 people, and O = 194,400 people
