You are studying two linked, autosomal genes (A and B) in Drosophila. You make the following testcross between AB/ab (x) ab/abflies, and record the progeny results (see below). However, you have previously determined that the Aa/bb genotype is lethal in early embryogenesis (before hatching), and therefore these individuals never appear among the viable testcross progeny observed. Indicate the most accurate map distance between the A and B genes that can be determined from these data? Show all your work (scratch...
