If a pollen of a flower falls on the stigma of another flower belonging to the same plant it is

Options

A. Ecologically cross - pollination
B. Genetically and ecologically cross pollination
C. Genetically self-pollination and ecologically cross-pollination
D. None of these

Answer

To solve the question "If a pollen of a flower falls on the stigma of another flower belonging to the same plant it is," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pollination**:
- Pollination is the process where pollen grains from the anther of one flower are transferred to the stigma of another flower.

2. **Identifying the Type of Pollination**:
- There are two main types of pollination: self-pollination and cross-pollination.
- Self-pollination occurs when pollen from the same flower or another flower on the same plant fertilizes the ovule.
- Cross-pollination occurs when pollen from one plant fertilizes the ovule of a different plant.

3. **Analyzing the Given Condition**:
- The question specifies that the pollen falls on the stigma of another flower belonging to the same plant.
- This indicates that the pollen is coming from one flower and landing on a different flower of the same plant.

4. **Determining the Correct Terminology**:
- Since the pollen is from one flower to another flower of the same plant, this situation can be classified as self-pollination because both flowers share the same genetic makeup.
- However, since the pollen is transferred between two different flowers, it can also be referred to as cross-pollination in an ecological context.

5. **Conclusion**:
- Therefore, the correct answer is that this type of pollination is both "genetically self-pollination" and "ecologically cross-pollination."

### Final Answer:
The correct answer is: **Genetically self-pollination and ecologically cross-pollination.**
