An Hfr strain with genotype A B C D (each gene for amino acid synthesis )and that transfers the A gene very late was mated with recipient strain with genotype a b c d. After mating for several hours, the mixture was diluted and plated on minimal media with four different supplements having various number of colony

Media supplement with amino acid  

                 Colony                                          number

                  A+C                                                 500

                  C+D                                                  50

                     B                                                    10

                     A                                                   250
