Answer

To solve the question regarding the number of parents involved in Apomixis and Amphimixis, we can follow these steps:

### Step-by-Step Solution:

1. **Define Apomixis**:
- Apomixis is a form of asexual reproduction that occurs in some plants where seeds are produced without fertilization. This means that the embryo develops from an unfertilized ovule.

2. **Determine the number of parents in Apomixis**:
- Since Apomixis does not involve fertilization, it typically involves only one parent plant. Therefore, the number of parents involved in Apomixis is **1**.

3. **Define Amphimixis**:
- Amphimixis refers to sexual reproduction in plants, which involves the fertilization of an egg by a sperm cell. This process requires the involvement of male and female gametes.

4. **Determine the number of parents in Amphimixis**:
- In Amphimixis, fertilization occurs, which means that both a male and a female parent are involved. Therefore, the number of parents involved in Amphimixis is **2**.

5. **Summarize the findings**:
- For Apomixis: 1 parent
- For Amphimixis: 2 parents

6. **Select the correct option**:
- Based on the analysis, the correct answer is that the number of parents involved in Apomixis and Amphimixis, respectively, is **1 and 2**.

### Final Answer:
The number of parents involved in Apomixis and Amphimixis, respectively, is **1 and 2**.
