Two Hfr strains are isolated from a prototrophic Str(s) F+ E. coli strain. Both Hfr strains are mated with a Str(r) F- E. coli strain that is mutant for all the genes listed. The following data are the times in minutes when the first recombinant progeny for each particular gene are observed following the start of mating.

Hfr A

arg+ = 35

aro+ = 21

asp+ = 62

man+ = 33

pur+ = 15

ser+ = 56

val+ = 88

Hfr B

arg+ = 6

aro+ = 20

asp+ = 69

man+ = 8

pur+ = 26

ser+ = 75

val+ = 43

6. Where would Hfr B be integrated on this map?
