Segeration of genes take place during

Options

A. Metaphase
B. Anaphase
C. Prophase
D. Embryo formation

Answer

**Step-by-Step Solution:**

1. **Understanding Gene Segregation**: Gene segregation refers to the process where alleles (different forms of a gene) separate during the formation of gametes. This is a key principle of Mendelian genetics.

2. **Identifying the Stages of Cell Division**: The process of segregation occurs during cell division, specifically during meiosis and mitosis. The stages of cell division include prophase, metaphase, anaphase, and telophase.

3. **Analyzing Each Stage**:
- **Prophase**: This is the stage where chromosomes condense and become visible. Homologous chromosomes pair up, but segregation has not yet occurred.
- **Metaphase**: In this stage, chromosomes align at the cell's equatorial plane. While this is crucial for proper segregation, the actual separation of alleles does not occur here.
- **Anaphase**: This is the critical stage where the spindle fibers shorten, pulling the sister chromatids (or homologous chromosomes in meiosis) apart towards opposite poles of the cell. This is where the segregation of genes occurs.
- **Embryo Formation**: This is not a stage of cell division but rather a developmental stage after fertilization.

4. **Conclusion**: Based on the analysis, the segregation of genes occurs during the anaphase stage of cell division.

5. **Final Answer**: The correct option is **anaphase**.
