Show transcribed image text Genie Geneticist has isolated two mutations in bacteriophage. One mutation causes clear plaques (c) and the other produces minute plaques (m). Previous mapping experiments have established that the genes responsible for these two mutations are 8 map units apart. Genie mixes the c^+m^+ phages with the c^- m^- phages and uses the mixture to infect bacterial cells. She then collects the progeny phages and cultures a sample of them on plated bacteria. A total of 1000 plaques are observed. How many of the different plaque types: c^+m^+ ; c^+ m^- ; c^- m^+; c^- m^- should Genie expect to see?
