In a dihybrid female fruit fly with genotype AaBb,88% of the meiosis there are no chiasmata between the A and B loci,and in 12% there is one.What is the expected frequency of recombinant gametes produced by this fly?

Recombinant gametes are produced through crossing over during meiosis. Given that 12% of meiosis events have a chiasma between the A and B loci, half of these will result in recombinant gametes. Therefore, the expected frequency of recombinant gametes is 12% / 2 = 6%.
