In sweet Pea , the flower colour changes from Red to white and seed coat colour from grey to white. This is an example of

Options

A. Spontaneous mutation
B. Pleitropic mutation
C. Reverse mutation
D. Induced mutation

Answer

**Step-by-Step Solution:**

1. **Understanding the Changes**: The question states that in sweet pea, the flower color changes from red to white and the seed coat color changes from grey to white. We need to identify the type of mutation that causes both these changes simultaneously.

2. **Identifying the Options**: The options provided are:
- Spontaneous mutation
- Pleiotropic mutation
- Reverse mutation
- Induced mutation

3. **Analyzing Each Option**:
- **Spontaneous Mutation**: This refers to mutations that occur naturally without any external influence. However, the question does not specify that the mutations are spontaneous.
- **Pleiotropic Mutation**: This type of mutation occurs when a single gene affects multiple phenotypic traits. Since both flower color and seed coat color are changing, this suggests a single gene is influencing both traits.
- **Reverse Mutation**: This refers to a mutation that restores the original phenotype. The question does not indicate that the traits are reverting to their original forms.
- **Induced Mutation**: This type of mutation is caused by external factors, such as chemicals or radiation. The question does not mention any external influence causing these changes.

4. **Conclusion**: Given that both the flower color and seed coat color changes are likely influenced by a single gene, the correct answer is **pleiotropic mutation**. This is because pleiotropy refers to a single gene affecting multiple traits.

5. **Final Answer**: The example described in the question is an example of **pleiotropic mutation**.
