Q7 - Hardy-Weinberg Analysis of the MN Blood Group
Among 1290 individuals of a population under study, the numbers of individuals with blood group types M, MN, and N are, respectively, 340, 880, and 70.
Using the information and data, determine which of the statements are true or which are false.
A. Based on the data, the frequencies of M and N alleles in the population are, respectively, 0.7 and 0.3.
B. The population describe above is in Hardy Weinberg equilibrium with respect to alleles of the MN blood group.
C. If there is random mating in a population in which frequency of M alleles is 0.6 and frequency of N alleles is 0.4, the frequency of offspring with the NN genotype will be 0.16.
D. In a start generation with frequency of M = 0.6 and frequency of N = 0.4, after three generations of random mating the frequency of MM individuals in the population of the fourth generation who are offspring of MN*MN matings will be <10%.
