Which following homologous structures are mismatched

Options

A. Clitoris and penis
B. Vagina and prostatic utricle
C. Scrotum and labia majora
D. Fallopian tube and prostate

Answer

To determine which homologous structures are mismatched, follow these steps:

### Step-by-Step Solution:

1. **Understand Homologous Structures**:
- Homologous structures are anatomical features that have a similar origin but may serve different functions in different species or contexts.

2. **Analyze the Options**:
- **Option 1: Tertorius and Penis**:
- Both structures are derived from the same embryonic tissue and serve different functions.
- **Option 2: Vagina and Prostatic Utricle**:
- These structures also share a common embryonic origin but have different functions.
- **Option 3: Scrotum and Labia Majora**:
- The scrotum in males and labia majora in females are derived from the same tissue and serve different roles.
- **Option 4: Fallopian Tube and Prostate**:
- The fallopian tube is a reproductive duct in females, while the prostate is a gland in males. They have different origins and functions.

3. **Identify the Mismatched Pair**:
- Upon analyzing the functions and origins, the fourth option (Fallopian tube and Prostate) is mismatched because they do not share a common embryonic origin; one is a duct and the other is a gland.

4. **Conclusion**:
- The mismatched pair of homologous structures is **Fallopian Tube and Prostate**.

### Final Answer:
The mismatched homologous structures are **Fallopian Tube and Prostate**.
