Three interrupted mating experiments were conducted using 3 different strains of prototrophic donor bacteria. The following entry times were obtained for the loci in the 3 donor strains. The times are given in minutes after the start of transfer. Determine the map of the bacterial chromosome from these data. Use the map to answer the question below. Hfr 1 Hfr 2 Hfr 3 A 12 - 10 B 31 - - C - 31 85 D - - 34 E - 26 - F 49 6 - What is the shortest distance between B and C?
