Calculate the frequencies of the M and N alleles in this population. What are the expected numbers of individuals of each genotypic class in this population? Assume Hardy-Weinberg conditions. Use the chi-squared test to determine if these data fit the Hardy-Weinberg equilibrium model.          The degrees of freedom for this test should be 1. Why is this appropriate?

                     61

              MN

                     64

                N

                     27

 

  1. Calculate the frequencies of the M and N alleles in this population.
  2. What are the expected numbers of individuals of each genotypic class in this population? Assume Hardy-Weinberg conditions.
  3. Use the chi-squared test to determine if these data fit the Hardy-Weinberg equilibrium model.

         The degrees of freedom for this test should be 1. Why is this appropriate?
