Question

the map positions of drosophila x linked recessive traits vermillion eye (v) miniature wings(m) and sable body (s) are33,36,and 43 in that order. A three hybrid cross of a wild type female heterozygous for all three traits gave a recombination frequency between vermillion eye and sabke bodyof 0.0985. a) calculate the interference b) if you were to cross v s+ m/v+ s m+ female flies to wild type males what fraction of the males do you expect to be triple mutant ( vermillion eye , immature wings, and sable body? C) what fraction of the progeny from the cross in b) do you expect to be miniature wings and sable body. Show every single step and explain in words each step.
