The locus B on the X chromosome of a malaria-carrying mosquito shows a 49% recombination rate with respect to the locus M
Since a recombination rate of 50% is essentially indistinguishable from independent assortment, you might be tempted to look for a locus that falls between B and M. Before you decide to do all that work, you run a chi square test to determine the P value of your experiment. Which of the following P values would be most likely to tell you that you should accept the conclusion that locus B and locus M are, indeed, 49mu apart and that another locus is not necessary? A. P = 0.45 B. P = 0.07 C. P = 0.05 D. P = 0.0007
