Unformatted text preview: what fraction would be expected to be: Genotype Fraction I A1 i 0.75 = 3/4 I A2 i 0.25 = 1/4 Among individuals of genotype I A I A , what fraction would be expected to be: Genotype Fraction I A1 I A1 0.5625 I A1 I A2 0.375 I A2 I A2 0.0625 In the same Maori population, the frequencies of individuals with B or AB blood are both less than 1%, while the frequency of individuals with O type blood is 49%. Complete the chart below with an estimate (to the nearest 5%) of the expected genotype frequencies (assuming HardyWeinberg equilibrium) in the population as a whole. Genotype Genotype frequency I A1 I A1 0.0506 I A1 I A2 0.0338 I A2 I A2 0.0056 I A1 i 0.315 I A2 i 0.105 Extra Credit (2 points) In the spaces below, provide two possible explanations for the existence of any Maoris with B or AB type blood.
