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 = 0.01
C) P = 0.005
D) P = 0.0007

A P value of 0.45 suggests that there is a high probability that the observed recombination rate of 49% is not significantly different from what would be expected if the loci B and M were 49 map units apart, indicating that another locus may not be necessary to explain the observed recombination rate.
