The second division in meiosis is called

Options

A. Reductional division
B. Multiplied division
C. Equational division
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a specialized type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs). It consists of two sequential divisions: Meiosis I and Meiosis II.

2. **Identifying the Divisions**:
- **Meiosis I**: This is known as the reductional division because it reduces the chromosome number from diploid (2n) to haploid (n). For example, in humans, the diploid number is 46 (2n = 46), and after Meiosis I, it reduces to 23 (n = 23).
- **Meiosis II**: This division is similar to mitosis and is referred to as the equational division. In this phase, the two haploid cells produced in Meiosis I divide again, but the chromosome number remains the same (haploid).

3. **Conclusion**: The second division in meiosis, which is Meiosis II, is called the equational division. This is because it does not change the chromosome number; it simply separates the sister chromatids of each chromosome.

4. **Final Answer**: The second division in meiosis is called **equational division**.
