The normal body cell of an organism contains 28 pairs of chromosomes. The number of chromosomes present in its germ cell will be :

Options

A. 28
B. 14
C. 56
D. 42

Answer

To determine the number of chromosomes present in the germ cell of an organism that has 28 pairs of chromosomes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Chromosome Count in Body Cells**:
- The organism has 28 pairs of chromosomes in its normal body cells.
- Since each pair consists of 2 chromosomes, the total number of chromosomes in body cells can be calculated as:
\[ \text{Total chromosomes} = \text{Number of pairs} \times 2 = 28 \times 2 = 56 \]

2. **Identify Germ Cells**:
- Germ cells, also known as gametes, are involved in sexual reproduction.
- Germ cells are haploid, meaning they contain half the number of chromosomes compared to body cells.

3. **Calculate the Number of Chromosomes in Germ Cells**:
- Since the body cells are diploid (2n), the germ cells will have half the total number of chromosomes:
\[ \text{Number of chromosomes in germ cells} = \frac{\text{Total chromosomes in body cells}}{2} = \frac{56}{2} = 28 \]

4. **Conclusion**:
- Therefore, the number of chromosomes present in the germ cell will be 28.

### Final Answer:
The number of chromosomes present in its germ cell will be **28**.
