This stage is called as 'Dyad of cells'

Options

A. Anaphase-I
B. Telophase-I
C. Metaphase-I
D. Prophase-I

Answer

To solve the question "This stage is called as 'Dyad of cells'", we need to identify which stage of the cell cycle is referred to as the "Dyad of cells".

### Step-by-step Solution:

1. **Understanding the Term 'Dyad of Cells'**:
- The term 'Dyad' refers to a pair of homologous chromosomes that are present after the process of meiosis, specifically after the first meiotic division.

2. **Identifying the Stages of Meiosis**:
- Meiosis consists of two main stages: Meiosis I and Meiosis II. Each of these stages has several phases: prophase, metaphase, anaphase, and telophase.

3. **Analyzing Each Phase**:
- **Prophase I**: Chromosomes condense and the nucleolus disappears. This is not the correct stage for 'Dyad of cells'.
- **Metaphase I**: Bivalents (paired homologous chromosomes) align at the metaphase plate. This stage does not represent the 'Dyad of cells'.
- **Anaphase I**: Homologous chromosomes are separated and pulled towards opposite poles. This is also not the 'Dyad of cells'.
- **Telophase I**: The separated chromosomes (now dyads) reach the poles, the nucleolus reappears, and cytokinesis occurs, leading to the formation of two daughter cells.

4. **Conclusion**:
- The 'Dyad of cells' is formed during **Telophase I** of meiosis when the chromosomes have reached the poles and the cell is preparing to divide.

### Final Answer:
The stage referred to as 'Dyad of cells' is **Telophase I**.
