Which of the following best describes why mapping is most accurate when genes are close together on a chromosome?

A) Double crossover events yield a result that looks the same as no crossover in a two gene mapping experiment and this throws off the calculations. B) This is not true; relative distance of two loci on a chromosome has no effect on accuracy of mapping. C) Double crossover events yield a result that looks the same as one crossover in a two gene mapping experiment and this throws off the calculations. D) The centromere gets in the way. E) This is not true; mapping genes is most accurate when genes are far away from each other.
