The type of pollination which is considered as functionally cross-pollination but genetically self- pollination is

Options

A. Xenogamy
B. Autogamy
C. Allogamy
D. Geitonogamy

Answer

To solve the question regarding the type of pollination that is functionally cross-pollination but genetically self-pollination, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Pollination**:
- **Xenogamy**: This is the fertilization process involving pollen from a genetically different plant. Hence, it is considered cross-pollination both functionally and genetically.
- **Autogamy**: This refers to self-fertilization where the pollen from the same flower fertilizes its ovules. This is purely self-pollination.
- **Allogamy**: This involves cross-fertilization between different plants, but it does not necessarily mean the plants are genetically different.
- **Geteno-gamy**: This is a type of self-pollination where pollen from one flower fertilizes the ovule of another flower on the same plant.

2. **Analyze the Options**:
- **Option 1 (Xenogamy)**: Incorrect, as it involves different plants.
- **Option 2 (Autogamy)**: Incorrect, as it involves self-pollination.
- **Option 3 (Allogamy)**: Incorrect, as it does not guarantee genetic difference.
- **Option 4 (Geteno-gamy)**: This is the correct option because it involves pollen from one flower fertilizing the ovule of another flower on the same plant, making it functionally cross-pollination but genetically self-pollination.

3. **Conclusion**:
- The type of pollination that is functionally cross-pollination but genetically self-pollination is **Geteno-gamy**.

### Final Answer:
**Geteno-gamy** is the correct answer.
