Identify the number of chromosomes in human germ cell.

Options

A. 23
B. 46
C. 92
D. 23 in males and 46 in females

Answer

To determine the number of chromosomes in a human germ cell, we need to understand the basic concepts of human genetics and cell division.

### Step-by-Step Solution:

1. **Understanding Germ Cells**: Germ cells are the reproductive cells in humans, which include sperm in males and eggs (ova) in females. These cells are responsible for passing genetic information to the next generation.

2. **Chromosome Count in Humans**: Humans have a total of 46 chromosomes arranged in 23 pairs. This includes 22 pairs of autosomes and 1 pair of sex chromosomes (XX in females and XY in males).

3. **Haploid vs. Diploid**: Germ cells are haploid, meaning they contain half the number of chromosomes compared to somatic (body) cells. Somatic cells are diploid, containing 46 chromosomes (23 pairs).

4. **Determining the Number of Chromosomes in Germ Cells**: Since germ cells are haploid, they contain only one set of chromosomes. Therefore, the number of chromosomes in a human germ cell is 23.

5. **Conclusion**: The correct answer to the question is that a human germ cell has 23 chromosomes.

### Final Answer:
The number of chromosomes in a human germ cell is **23**.
