In the meiotic cell division four daughter cells are produced by two successive divisions in which :

Options

A. first division is equational and second is reductional
B. first division is reductional and second is equational
C. both divisions are reductional
D. both divisions are equational

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It results in the formation of four daughter cells from one mother cell.

2. **Phases of Meiosis**: Meiosis consists of two distinct phases: Meiosis I and Meiosis II. Each phase has its own specific functions and outcomes.

3. **Meiosis I - Reductional Division**: In Meiosis I, the mother cell (which is diploid, 2n) divides to form two daughter cells (haploid, n). This phase is called reductional division because the chromosome number is halved.

4. **Meiosis II - Equational Division**: In Meiosis II, the two haploid daughter cells from Meiosis I undergo division again, resulting in a total of four haploid daughter cells. This phase is similar to mitosis and is called equational division because the chromosome number remains the same (haploid, n).

5. **Conclusion**: Therefore, in meiotic cell division, four daughter cells are produced by two successive divisions where the first division (Meiosis I) is reductional and the second division (Meiosis II) is equational.

**Final Answer**: In meiotic cell division, four daughter cells are produced by two successive divisions in which the first division is reductional and the second division is equational.
