There are two mutations in bacteriophage. One mutation causes
clear plaques (c) and the other produces minute plaques (m). The
genes responsible for these two mutations are 8 map units apart.
You mix phage of genotype c+ m+ with phage of genotype c- m- and
infect bacterial cells. Of the 1000 plaques that result, how many
should have the genotype c+ m-?
