Assume a diploid, single-gene system with 2 alleles, A1 and A2. The frequency of A1 is 0.7 in the parental generation

(a) If we assume random mating and a large population size (H-W equilibrium), what are the
genotype frequencies in the F1 generation?

(b) If all individuals homozygous for A2 die in the F1 generation as nearly mature adults before mating, what are the allele frequencies in the F1 that contribute to the next generation?
