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+ What is the correct order of genes on this bacterial chromosome?
