The major importance of meiosis lies in

Options

A. Development of mutations
B. Sexual reproduction
C. It transfers chromosomes through mitosis
D. It maintains chromosome number generation after generation

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a specialized type of cell division that reduces the chromosome number by half, resulting in the formation of four haploid cells from one diploid parent cell. This is crucial for sexual reproduction.

2. **Formation of Gametes**: During meiosis, gametes (sperm and egg cells) are produced. These gametes are haploid, meaning they contain only one set of chromosomes.

3. **Restoration of Chromosome Number**: When two haploid gametes fuse during fertilization, they form a diploid zygote. This process restores the original chromosome number of the species, ensuring that it remains constant from generation to generation.

4. **Evaluating the Options**:
- **Option 1 (Development of mutation)**: This is incorrect as meiosis does not directly relate to the development of mutations.
- **Option 2 (Sexual reproduction)**: While meiosis is involved in sexual reproduction, it is not the primary importance of meiosis.
- **Option 3 (Transfers chromosome through mitosis)**: This is incorrect because meiosis and mitosis are different processes. Mitosis does not transfer chromosomes; it replicates them.
- **Option 4 (Maintains chromosome number generation after generation)**: This is the correct answer, as the primary importance of meiosis is to maintain the chromosome number across generations.

5. **Conclusion**: The major importance of meiosis lies in the maintenance of chromosome number generation after generation, making option 4 the correct choice.
