An Hfr strain that is hisE+
was mated to a strain that is hisE-
. The mating was interrupted and the percentage of recombinants for each gene was determined by streaking onmedia that lacked either histidine or phenylalanine. The following results were obtained:
A. Determine the map distance (in minutes) between these two genes.
B. In a previous experiment, it was found that hisE is 4 minutes away from the gene pabB. PheA was shown to be 17 minutes from this gene. Draw a genetic map describing the locationsof all three genes.
