NEETBotanyCell Cycle and Cell Division
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Meiosis II is considered an equational division and resembles normal mitosis. Reason (R): During Meiosis II, homologous chromosomes separate, reducing the chromosome number to half. In the light of the above statements, choose the correct answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is correct but (R) is not correct
- D(A) is not correct but (R) is correct
Correct answer
C. (A) is correct but (R) is not correct
Step-by-step solution
The Assertion is correct because Meiosis II resembles normal mitosis; it is an equational division where the chromosome number remains the same as it was at the end of Meiosis I. The Reason is incorrect because the separation of homologous chromosomes occurs during Anaphase I of Meiosis I, which is the actual reductional step. During Meiosis II, the sister chromatids separate, and the chromosome number is not reduced further. Answer: (A) is correct but (R) is not correct
