Q. You are checking the sequence of 3 genes using generalized transduction mapping. The recipient is Leu-, Aziˢ, Thr- while the donor is Leu+, Aziᴿ, Thr +. If you select the Leu+ as marker, Aziᴿ would be 50% while Thr+ would be 2%. If you select Thr+ as marker Leu+ would be 3% and Aziᴿ would be 0%. What is the sequence?
