Any help would be greatly appreciated thank you

With the technique of interrupted mating four Hfr strains were tested for tile sequence in which they transmitted a number of different genes to an F strain. Each Hfr strain was found to transmit its genes in a unique [sequence, as shown in the accompanying table (only the |first six genes transmitted wore scored for each strain). What is the gene sequence in the original strain from which these Hfr strains derive? Indicate on your diagram the origin and polarity of each of the four Hfr's.

Explanation / Answer

Hfr will pick up all the intermediates between any two genes. So, the gene sequence in the original strain from which these Hfr strains are derived is OFBAEMBAEXCRHG

All these Hfr strains are derived from the same F+ strain.
