A cross is made between an Hfr that is met+ thi+ pur+ and an F-that is met- thi- pur-. Interrupted mating studies show that met+ enters the recipient last, so met+ recombinants are selected on a medium containing supplements that satisfy only the pur and thi requirements. These recombinants are tested for the presence of the thi+ and pur+ alleles. The following numbers of individuals are found for each genotype:
|
A) Gene Order |
I |
Thi Pur Met |
|
II |
Pur Met Thi |
|
|
III |
Pur Thi Met |
|
|
B) Distance between Pur and Thi |
