Which one of the following pair of reproductive organs does not show homology between males and females ?

Options

A. Glans penis & Clitoris
B. Scrotum & Labia minora
C. Bulbourethral gland & Bartholin's gland
D. Prostate gland & Skene's gland

Answer

To solve the question of which pair of reproductive organs does not show homology between males and females, we need to analyze the options provided and understand the concept of homology in biological terms.

### Step-by-Step Solution:

1. **Understand Homology**:
- Homologous structures are those that have a similar origin and structure but may serve different functions. In the context of reproductive organs, homologous structures in males and females perform similar roles in reproduction.

2. **Analyze the Options**:
- We have several pairs of reproductive organs to consider:
- **Glands: Penis and Clitoris**: Both are sensitive structures involved in sexual arousal and pleasure. They are homologous.
- **Scrotum and Labia Minora**: The scrotum is a pouch that holds the testes and regulates temperature for sperm production, while the labia minora are folds of skin that protect the vaginal opening. They do not perform similar functions, indicating they are not homologous.
- **Bulbourethral Gland and Bartholin's Gland**: Both glands provide lubrication during sexual arousal, making them homologous.
- **Prostate and Skene's Gland**: Both contribute to the production of fluids that support sperm and lubrication, indicating they are homologous.

3. **Identify the Correct Answer**:
- From the analysis, the pair that does not show homology is **Scrotum and Labia Minora**. They serve different functions and do not have a similar origin.

### Final Answer:
The pair of reproductive organs that does not show homology between males and females is **Scrotum and Labia Minora**.
