If the a and b loci are 40 cm apart and an aa bb individual and an aa bb individual mate: a. what gametes will the f1 individuals produce, and in what proportions? what phenotypic classes in what proportions are expected in the f2 generation (assuming complete dominance for both genes)? b. if the original cross was aa bb x aa bb, what gametic proportions would emerge from the f2? what would be the result in the f2 generation?
