Meiosis is

Options

A. Multiplicational division
B. Equational division
C. Disjunctional division
D. Reductional division

Answer

**Step-by-Step Solution:**

1. **Definition of Meiosis**: Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It is essential for the production of gametes (sperm and egg cells).

2. **Types of Division**: Meiosis is often referred to as a "reductional division." This means that the chromosome number is reduced by half during the process.

3. **Process of Meiosis**: The meiosis process consists of two successive rounds of cell division:
- **First Meiotic Division (Meiosis I)**: This division separates homologous chromosomes, resulting in two daughter cells. Each of these cells contains the same number of chromosomes as the original cell (diploid).
- **Second Meiotic Division (Meiosis II)**: This division separates sister chromatids in each of the two cells produced from Meiosis I, resulting in four haploid cells.

4. **Outcome of Meiosis**: The end result of meiosis is four haploid cells, each with half the number of chromosomes compared to the original diploid cell. For example, if the original cell had 46 chromosomes, each of the four resulting cells will have 23 chromosomes.

5. **Conclusion**: Based on the characteristics and outcomes of meiosis, it is correctly identified as a "reductional division."

**Final Answer**: The correct answer is that meiosis is a "reductional division."
