Answer :
In the next generation, after the mutation, we can calculate the frequencies of the alleles using the Hardy-Weinberg equations. Let p represent the frequency of the A allele (A1) and q represent the frequency of the a allele (A2). The frequency of the A1 allele in the next generation (A1') can be calculated as p' = p - up, where u is the mutation rate.
(a) To calculate A1 in the next generation, we substitute the values into the equation: A1' = 0.7 - (0.7 * 0.03) = 0.679.
(b) Similarly, the frequency of the A2 allele in the next generation (A2') can be calculated as q' = q - up. In this case, since A1 mutated to A2, we can use the same mutation rate: A2' = 0.03.
(c) The expected frequency of A1A2 (heterozygotes) in the next generation can be calculated as 2p'q'. Substituting the values, we get: A1A2' = 2 * 0.679 * 0.03 = 0.04074.
In summary, in the next generation, the frequency of A1 is expected to be 0.679, the frequency of A2 is expected to be 0.03, and the expected frequency of A1A2 heterozygotes is 0.04074. These calculations are based on the assumption of Hardy-Weinberg equilibrium and the given mutation rate.
