Through PCR, we have determined the PER3 genotypes for a class of students as follows:

H4/H4 = 125 individuals; H4/H5 = 90 individuals and H5/H5=85 individuals.

Considering the Hardy Weinberg equilibrium and comparing the observed and the expected number of individuals for the three genotypes, calculate the value of the Chi-square statistic. Select only one answer.
