WebThe class of admissible tests for Hardy-Weinberg equilibrium in a multi-allelic system is characterized. The standard goodness-of-fit chi-square tests is shown to be admissible … WebWith 2 degrees of freedom (3 genotypes - 1), the p-value associated with a chi-square value of 274.37 or higher is less than 0.001. This indicates a significant departure from Hardy-Weinberg equilibrium in this population. Therefore, we can conclude that the population is not in Hardy-Weinberg equilibrium. Ans. e.
