The Locus B on the X Chromosome of a Malaria-Carrying

question 19

Multiple Choice

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
