A donor strain of bacteria with genotype leu* gal pro* is infected with phages. The phage lysate from the bacterial cells is collected and used to infect a second strain of bacteria that are leu gal* pro". The second strain is selected for leu", and the following cotransduction data are obtained: Cells with cotransduced allele (%) Selected Donor Recipient allele leu* leu" gal* leu* 47 pro* gal" pro* pro leu* 26 gal" Which genes are closest, leu and gal or leu and pro?
