  • The following figure depicts the relationship between a genetic map for four genes (A, B, C and D) and their corresponding physical map: <img alt="" src="https://cdn.entrance360.com/

The following figure depicts the relationship between a genetic map for four genes (A, B, C and D) and their corresponding physical map:

The following statements are made to explain this relationship:

1. More recombination events occur between A and B as compared to B and C.

2. Lesser number of recombination events occur between C and D as compared to B and C.

3. Although the physical distance between A and B is less than that between C and D, the region between A and B is more recombinogenIc.

4. The physical distance between A and B is less than that between C and D, and thus the region between A and B is less recombinogenic.

5. Although the physical distance between C and D is more than that between B and C, the region between C and D is less recombinogenic.

6. Although the physical distance between C and D is more than B and C, the region between C and b is more recombinogenIc.

Which statements are correct?

 

Option: 1

1 and 2


Option: 2

3 and 5


Option: 3

4 and 6


Option: 4

More recombination events occur between A and B as compared to B and C.

Based on the genetic map distances provided (10 cM each), there is no indication that there would be more recombination events between A and B compared to B and C. Therefore, statement 1 is incorrect.

Lesser number of recombination events occur between C and D as compared to B and C.
Again, based on the given genetic map distances (10 cM each), there is no indication that there would be fewer recombination events between C and D compared to B and C. Therefore, statement 2 is incorrect.

Although the physical distance between C and D is more than B and C, the region between C and B is more recombinogenic.

There is no specific information given regarding the relationship between C and B, so statement 6 cannot be evaluated based on the given information.

Therefore, statements 3 and 5 are correct. Hence, the correct answer is option 2.
