In a second study group, the frequencies of the genotypes were 0.306 MM, 0.491 MN, and 0.203 NN. ...

The M and N factors are glycoproteins on the surface of red blood cells. Unlike other types of red blood cell antigens, the M and N factors do not cause antibody reactions in human blood transfusions. People with type M blood are homozygous for the M allele, and people with type N blood are homozygous for the N allele. Heterozygous individuals have type MN blood. In a study of a population of Inuit living in the Northwest Territories, blood type M had a frequency of 0.66, blood type MN had a frequency of 0.31, and blood type N had a frequency of 0.03.

Question:
In a second study group, the frequencies of the genotypes were 0.306 MM, 0.491 MN, and 0.203 NN. Could this second study group have come from the previously described Inuit population? Explain your answer.
