Question

Eight roll mutants of phage T4 are isolated and crossed in all pair wise combinations to determine which mutation pairs can recombine to form wild-type progeny. the results of these mapping crosses are summarized on the right [+ = WT recombinants formed; 0 = no WT recombinants formed]. Draw a genetic map of these eight mutations. Place point mutations in their correct relative order on a line representing the roll region and place deletions below the line to show the extent of roll material that each is lacking. Clearly label all point and deletion mutations and indicate
