Q. In a population of 278, if observed number of MM, MN and NN blood groups is 78,138 and 62 respectively, what would be the frequency of M?

EAMCETEAMCET 2006

Solution:

Proportion of MM blood group in the population = $ \frac{78}{278}=.280 $ Proportion of MN blood group in the population = $ \frac{138}{278}=.496 $ Proportion of NN blood group in the population = $ \frac{62}{278}=.223 $ Frequency of M = $ \frac{2\times .280+.496}{2}=.53 $ Frequency of N = $ \frac{2\times .223+.496}{2} $ =.47
