Male XX and female XY sometime occur due to :

Options

A. Deletion
B. Transfer of segments in X and Y chromosome
C. Aneuploidy
D. Hormonal imbalance

Answer

To solve the question regarding why male XX and female XY sometimes occur, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding Normal Chromosomal Patterns**:
- In typical human genetics, males have XY chromosomes while females have XX chromosomes. This is the standard chromosomal arrangement.

2. **Identifying the Anomalous Condition**:
- The question presents an unusual condition where males have XX chromosomes and females have XY chromosomes. This is not the norm and requires an explanation.

3. **Exploring Possible Causes**:
- To understand why this chromosomal arrangement occurs, we need to consider genetic and hormonal factors. The options provided in the question hint at various genetic anomalies.

4. **Evaluating the Options**:
- **Deletion**: This refers to the loss of a chromosome segment, which does not explain the XX male condition.
- **Transfer of segments between X and Y chromosomes**: This is also not a typical explanation for this chromosomal arrangement.
- **Unemployment**: This term does not apply to genetic conditions and is irrelevant in this context.
- **Hormonal Imbalance**: Hormonal factors can influence sexual development and can lead to atypical chromosomal expressions.

5. **Conclusion**:
- The correct answer is that the occurrence of male XX and female XY is due to **hormonal imbalance**. This imbalance can affect the development of sexual characteristics and chromosomal expression.

### Final Answer:
The male XX and female XY condition sometimes occurs due to **hormonal imbalance**.
