Options

A. Protandry
B. Herkogamy
C. Protogyny
D. Prepotency.

Answer

To solve the question regarding the condition of maturation of stigma before anthers of the same flower, we can analyze the options provided:

1. **Understanding the terms**:
- **Protandry**: This is when the male reproductive organs (stamens) mature before the female reproductive organs (carpels). This means that the anthers mature before the stigma. Therefore, this option is incorrect for our question.

2. **Evaluating the second option**:
- **Hercogamy**: This refers to a physical separation between the male and female reproductive parts in a flower to prevent self-pollination. Since this does not specifically address the maturation order of stigma and anthers, it is also an incorrect option.

3. **Analyzing the third option**:
- **Protogyny**: This is the condition where the female reproductive organs (stigma) mature before the male reproductive organs (anthers). This matches the question's requirement, making it the correct answer.

4. **Considering the last option**:
- **Prepotency**: This term refers to the ability of one parent to influence the hereditary traits of its offspring. It does not relate to the maturation of stigma and anthers, making it an incorrect option.

**Conclusion**: The correct answer is **Protogyny**, as it describes the condition where the stigma matures before the anthers in the same flower.
