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 considered functionally cross-pollination but genetically self-pollination, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Pollination**:
- **Self-Pollination**: This occurs when pollen from the same flower fertilizes its own ovules. It can happen in the same flower (autogamy) or between flowers of the same plant (geitonogamy).
- **Cross-Pollination**: This involves the transfer of pollen from one flower to the ovule of another flower, which can be between different plants (xenogamy) or different flowers of the same plant (geitonogamy).

2. **Analyze the Options**:
- **Xenogamy**: This is true cross-pollination between different plants.
- **Autogamy**: This is self-pollination within the same flower.
- **Allogamy**: This is another term for cross-pollination, usually between different plants.
- **Geitonogamy**: This is when pollen from one flower fertilizes the ovules of another flower on the same plant.

3. **Identify the Correct Term**:
- The question specifies that the process is functionally cross-pollination but genetically self-pollination.
- Geitonogamy fits this description because it involves pollen transfer between different flowers of the same plant (functionally cross-pollination), but since the pollen comes from the same plant, it is genetically self-pollination.

4. **Conclusion**:
- Therefore, the correct answer to the question is **Geitonogamy**.

### Final Answer:
**Geitonogamy**
