The significance of Meiosis is that it -

Options

A. Produce four cells having chromosomal number equal to mother cell
B. Occurs in all types of cells
C. Maintains the constant Chromosomes number to a particular species
D. Growth of animal body organs

Answer

**Step-by-Step Solution:**

1. **Understanding Meiosis**: Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It reduces the chromosome number by half, resulting in four haploid daughter cells from one diploid parent cell.

2. **Evaluating the Options**:
- **Option 1**: "Produce four cells having chromosome number that is equal to the mother cell."
- This statement is incorrect because meiosis results in daughter cells that have half the chromosome number of the mother cell.

- **Option 2**: "Occurs in all types of cells."
- This statement is also incorrect. Meiosis specifically occurs in germ cells (gametes), not in all types of cells. Mitosis occurs in somatic cells.

- **Option 3**: "Maintains the constant chromosome number to a particular species."
- This statement is correct. Meiosis ensures that when gametes fuse during fertilization, the resulting zygote has the same chromosome number as the species, thus maintaining genetic stability across generations.

- **Option 4**: "Growth of animal body organ."
- This statement is incorrect as growth and repair of body organs are primarily facilitated by mitosis, not meiosis.

3. **Conclusion**: The significance of meiosis is that it maintains the constant chromosome number of a particular species, making option 3 the correct answer.

**Final Answer**: The significance of Meiosis is that it maintains the constant chromosome number to a particular species.
