Question 6 In a population of mice the alleles for fur colour are co-dominant. Heterozygotes have yellow fur while homozygotes have either brown fur or white fur. There are 480 brown mice, 288 yellow mice, and 32 white mice in the population. [8] Use this information to calculate whether this population is in Hardy-Weinberg equilibrium. Show your calculations. x² = (0-E)² Hint: use the chi square formula E and the table below (df = 1) to find out if the allele frequencies are significantly different from Hardy-Weinberg at p < 0.05.
