WebIf a population is in Hardy-Weinberg equilibrium, allele frequencies will be related to genotype frequencies by a specific mathematical relationship, the Hardy-Weinberg equation. So, we can predict the genotype frequencies … Web2.2 Calculation of Chi-square test for deviation from Hardy-Weinberg equilibrium. - Put your observed numbers and click the Calculate button. The number of degrees of freedom for the chi-square is equal to one for two allele systems; and three for three allele systems; and six for four allele systems. The results are rounded (four decimals).
