Statement I: In mitosis, chromosomal number in the progeny as well as in parents remains the same
Statement II: Mitosis takes place in gametes
In light of the above statements, choose the most appropriate answer from the options given below:
1. Both statement I and statement II are correct
2. Both statement I and statement II are incorrect
3. Statement I is correct but statement II is incorrect
4. Statement I is incorrect but statement II is correct
Reason(R): This well coordinated way ensures correct division and formation of progeny cells containing intact genomes.
Choices for Assertions and reasons:
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
3. (A) is true, but (R) is false.
4. (A) is false, but (R) is true.
