Multiple Hfr strains of bacteria were used in an interrupted

Multiple Hfr strains of bacteria were used in an interrupted mating experiment designed to map the bacterial genome. After initial time mapping experiments the order of gene entry for the different Hfr strains were established and are listed below. Use these data to create map of the bacterial genome, be sure to indicate the origin and orientation of each Hfr strain.

Solution

Answer:

Arranging the genes in overlapping fashion:

KBIPG

PGAJF

AJFKB

So, the order of the genes and the orientation (from left to right, and can be arranged in clockwise direction with K at 12\'O clock position and G at 6\'O clock position)
