Question:
Assertion (A): Loss or gain of a segment of DNA results in alteration in chromosomes.
Reason (R): Alterations in chromosomes do not result in abnormalities.
Assertion (A): Loss or gain of a segment of DNA results in alteration in chromosomes.
Reason (R): Alterations in chromosomes do not result in abnormalities.
Reason (R): Alterations in chromosomes do not result in abnormalities.
Show Hint
Chromosomal alterations usually cause genetic abnormalities, not neutral outcomes.

- Both A and R are correct and R is the correct explanation of A.
- Both A and R are correct but R is not the correct explanation of A.
- A is correct but R is incorrect.
- A is incorrect but R is correct.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Chromosomal alterations such as deletion or duplication of DNA segments can lead to changes in chromosome structure and function, often resulting in genetic disorders or abnormalities. Hence, the assertion is correct, but the reason is false.
