8. If Researcher 2’s model is correct and an additional gene, Gene G, is 8 mu from Gene B and 14 mu from Gene D, then Gene G is most likely between:
Your Answer is
Correct Answer is H
Explanation
The stem says that the Model of Researcher 2 is correct, and the distance between Gene G and Gene B is 8 mu, and the distance between Gene G and Gene D is 14 mu. Gene G is closer to Gene B and farther to Gene D.
From the second Model in figure 3, it can be seen that D is on the left and B is on the right. Only when Gene G is on the right of Gene B can it ensure that it is closer to Gene B and farther from Gene D. In this way, Gene G has to be between Gene B and Gene C
