WebRecitation 6: Hardy-Weinberg Equilibrium (HWE) and Chi-square Test We observe the trait of face freckles ( F / f) within a population of 800 people in Mesa. For this assignment, assume freckles on the face are a heritable trait and are controlled by one gene, where F is dominant. The distribution of genotypes within this population are shown below in Table 1. WebChi-Square Goodness-Of-Fit Test Compares observed genotype counts with the values expected under Hardy-Weinberg. For a locus with two alleles, we might construct a table as follows: Genotype Observed Expected under HWE AA n AA np2 A Aa n Aa 2np A(1 p A) aa n aa n(1 p A)2 where n is the number of individuals in the sample and p A is the
