An Hfr strain that is hisE + and pheA + was mixed with a strain that is hisE and pheA . The conjugation was interrupted and the percentage of recombinants for each gene was determined by streaking on a medium 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 locations of all three genes.
