Q41 - Applying Hardy-Weinberg Equilibrium to the ABO Blood Group System
Frequencies of the human ABO blood group alleles in a population are p(IA) = 40%, p(IB) = 40% and p(i) = 20%. Assuming that the population is in Hardy-Weinberg equilibrium, indicate in the answer sheet if each of the following statements is true or false.
Using the information and data, determine which of the statements are true or which are false.
A. In this population, the number of persons with the blood groups A and B should be equal.
B. In this population, the number of persons with the blood groups A and AB should be equal.
C. In this population the frequency of persons with anti-B antibodies is 64%.
D. Locus AB0 is localized on an autosomal chromosome because the blood group frequencies are the same for men and women.
