Essay

The MN blood group in humans is under the control of a pair of codominant alleles,L^M and L^N.In a group of 556 individuals,the following genotypic frequencies are found:
$$\begin{array} { l l } 167 & M M \\280 & M N \\109 & N N\end{array}$$
a)Calculate the frequency of the L^M and L^N alleles.
b)Test (using the chi-squared test)whether the genotypic frequencies conform to the Hardy-Weinberg distribution.
