Figure 2.9 A x2 distribution with one degree of freedom. The x2 value for the Hardy-Weinberg test with MN blood group genotypes as well as the critical value to reject the null hypothesis are shown (see text for details). The area under the curve to the right of the arrow indicates the probability of observing that much or more difference between the observed and expected outcomes.

larger if the expected number is 8 (it is 50%). Adding all of these relative squared differences gives the total relative squared deviation observed over all genotypes.
