In gametogenesis , reduction division take place during :-

Options

A. Multiplication phase
B. Growth phase
C. first maturation division
D. Second maturation

Answer

**Step-by-Step Solution:**

1. **Understanding Gametogenesis**: Gametogenesis refers to the process of forming gametes (sperm and eggs) in organisms. This process is crucial for sexual reproduction.

2. **Identifying the Types of Cell Division**: In gametogenesis, two types of cell division occur: mitosis and meiosis. Mitosis is for growth and repair, while meiosis is specifically for producing gametes.

3. **Meiosis Overview**: Meiosis consists of two main stages: Meiosis I and Meiosis II. Meiosis I is known as the reduction division because it reduces the chromosome number by half, while Meiosis II is an equational division that does not change the chromosome number.

4. **First Maturation Division**: The first maturation division corresponds to Meiosis I, where the homologous chromosomes are separated, leading to a reduction in the chromosome number. This is where the reduction division takes place.

5. **Second Maturation Division**: The second maturation division corresponds to Meiosis II, which is not a reduction division but rather an equational division where sister chromatids are separated.

6. **Conclusion**: Therefore, in gametogenesis, the reduction division occurs during the first maturation phase, which is Meiosis I.

**Final Answer**: The reduction division in gametogenesis takes place during the **first maturation phase**.
