Segregation of genes occurs in

Options

A. Embryo formation
B. Anaphase I
C. Anaphase II
D. Metaphase II

Explanation

**Step-by-Step Solution:**

1. **Understanding Segregation of Genes**: The segregation of genes refers to the process where alleles of a gene separate during gamete formation, ensuring that each gamete carries only one allele for each gene.

2. **Identifying the Process**: Segregation occurs during meiosis, which is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs).

3. **Meiosis Stages**: Meiosis consists of two main stages: Meiosis I and Meiosis II.
- Meiosis I is known as the reductional division because it reduces the chromosome number from diploid (2n) to haploid (n).
- Meiosis II is similar to mitosis and is known as the equational division because it does not change the chromosome number.

4. **Focus on Meiosis I**: The segregation of genes specifically occurs during Meiosis I, particularly in the anaphase I stage. During anaphase I, homologous chromosomes are pulled apart to opposite poles of the cell.

5. **Conclusion**: Therefore, the correct answer to the question "Segregation of genes occurs in" is during **Anaphase I of Meiosis**.

**Final Answer**: The segregation of genes occurs in Anaphase I of Meiosis.
