Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected simultaneously with phage strains rII1 and rII2 at a high moi. The progeny phage are collected and used to infect cells of E. coli K. This infection is also carried out at a high m. o.i., and the resulting phage are collected. These progeny are diluted and plated on both E. coli B and E. coli K. Do you expect more plaques on strain B, on strain K, an equal amount on both or is it impossible to tell?
A. E. coli B
B. E. coli K
C. Equal on both
D. Can't tell
