Meiosis results in :–

Options

A. Half number of chromosome
B. Same number of chromosome
C. Double number of chromosome
D. 1/4 number of chromosome

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs in animals).

2. **Chromosome Count**: In humans, for example, somatic cells (body cells) have 46 chromosomes (23 pairs), which is referred to as diploid (2n). Meiosis takes a diploid cell and produces haploid cells (n), which contain half the number of chromosomes.

3. **Outcome of Meiosis**: The process of meiosis involves two rounds of division (Meiosis I and Meiosis II) and results in four daughter cells, each with half the number of chromosomes compared to the original diploid cell.

4. **Analyzing the Options**:
- **Option 1: Half number of chromosomes** - This is correct because meiosis produces haploid cells.
- **Option 2: Same number of chromosomes** - This is incorrect; this describes mitosis, not meiosis.
- **Option 3: Double number of chromosomes** - This is incorrect; meiosis does not double the chromosome number.
- **Option 4: 1/4 number of chromosomes** - This is also incorrect; meiosis results in half, not a quarter.

5. **Conclusion**: The correct answer is that meiosis results in half the number of chromosomes.

**Final Answer**: Meiosis results in half the number of chromosomes.
