Four Hfr stains of E. coli are known to transfer their genetic material during conjugation in different sequences. Given the time of entry of the markers into the F- recipient:
A. Construct a genetic map that includes all of these markers. (12 points)
B. Label the time distance between adjacent gene pairs. (11 points)
C. Indicate the points at which the F factor is located for each of the strains. (4 points)
