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	IV	15.4 map unit
	V	1.8 map unit
