When testing these results using a Chi-Square test, you rejected the null hypothesis that this population is in Hardy-Weinberg Equilibrium with p<0.001. You are interested in understanding what evolutionary mechanism may be most likely responsible for the significant deviations of observed genotype frequencies from Hardy-Weinberg proportions. First, let's describe the pattern of genotypes in relationship to expected genotype frequencies under Hardy-Weinberg. Choose... Observed frequency of AA genotype less frequent than expected more frequent than expected Observed frequency of Aa genotype 15 Tequeme APECCA Observed frequency of aa genotype more frequent than expected - Check
