Given: The null hypothesis is false in case of One-way ANOVA test.

Three alleles (alternative versions of a gene) A, B, and O determine the four blood types A (AA or AO), B (BB or BO), O (OO), and AB. The Hardy-Weinberg Law states that the proportion of Boas in a population who carry two different alleles is
$P=2pq+2pr+2rq$
where p, g, and rare the proportions of A, B, and O in the population.
Use the fact that $p+q+r=1$ to show that P is at most
$\frac{2}{3}.$
