question_answer 18)

  Distance between the genes and percentage of recombination shows (a) a direct relationship                                                 (b) an inverse relationship (c) a parallel relationship                                               (d) no relationship      

Answer:

                  (a) Crossing over separates genes away from each other. So, the distance between the genes and percentage of recombination shows an direct relationship, i.e., when genes are close together they have high linkage and exhibit low recombination frequencies. Thus, the other option is wrong as it does not show parallel or inverse relationship.
