An Hfr strain of E.coli with the genotype a+b+c+d+e+f+ is mated with an F- auxotrophic strain with the genotype a-b-c-d-e-f-.Conjugation is stopped at 10-minute intervals and the genotypes of the resulting conjugants are determined.The following results are obtained:
After 10 minutes e+
After 20 minutes a+e+
After 30 minutes a+b+e+
After 40 minutes a+b+d+e+
After 50 minutes a+b+c+d+e+
After 60 minutes a+b+c+d+e+f+
