Two mutations were isolated in a bacteriophage: one causing clear plaque (c) and the other causing minute plaque (m). The genes responsible are 9 cM apart. Plaques with genotype c+ m- and c- m+ were mixed to infect bacterial cells. Progeny plaques were collected and analyzed. Consider the following hypothetical experimental counts: A. c+ m+: 455, c+ m-: 45, c- m+: 45, c- m-: 455 B. c+ m+: 455, c+ m-: 455, c- m+: 45, c- m-: 45 C. c+ m+: 45, c+ m-: 455, c- m+: 455, c- m-: 45 D. c+ m+: 65, c+ m-: 680, c- m+: 685, c- m-: 70 Which of the statements correctly describe counts consistent with a recombination frequency of 9%?
