Chromosome number in meiocyte of human beings is

Options

A. 40
B. 42
C. 44
D. 46

Answer

To determine the chromosome number in a meiocyte of human beings, we can follow these steps:

### Step-by-step Solution:

1. **Understanding Meiocytes**:
- Meiocytes are specialized cells that undergo meiosis to produce gametes (sperm and eggs).

2. **Chromosome Count in Humans**:
- Human somatic (body) cells typically have 46 chromosomes, which are arranged in 23 pairs.

3. **Meiosis Process**:
- During meiosis, a meiocyte (diploid cell) undergoes two rounds of cell division (meiosis I and meiosis II).
- In meiosis I, the homologous chromosomes are separated, but the chromosome number remains the same (46 chromosomes).
- In meiosis II, the sister chromatids are separated, resulting in four haploid cells.

4. **Final Chromosome Count in Gametes**:
- After meiosis, each gamete (sperm or egg) will have half the number of chromosomes, which is 23.
- However, the meiocyte itself, before undergoing meiosis, contains 46 chromosomes.

5. **Conclusion**:
- Therefore, the chromosome number in a meiocyte of human beings is 46.

### Answer:
The chromosome number in meiocyte of human beings is **46**.
