Following table summarises the differences between self-fertilisation and cross-fertilisation. Pick out the wrong difference.

Options

A. `{:("Self-fertilisation","Cross-fertilisation"), (" It is uniparental.", "It is biparental."):}`
B. `{:("Self-fertilisation","Cross-fertilisation"), (" It involves the fusion of male and female gametes of the same parent.", "It involves the fusion of two gametes produces by different parents."):}`
C. `{:("Self-fertilisation","Cross-fertilisation"), ("Examples : Pheretima, Periplaneta", "Examples : Taenia, Rana tigrina"):}`
D. None of the above.

Explanation

To identify the wrong difference between self-fertilization and cross-fertilization, let's analyze the provided statements step by step.

### Step 1: Understand Self-Fertilization
Self-fertilization refers to the process where an organism fertilizes its own eggs with its own sperm. This means that both the male and female gametes come from the same individual (uniparental).

### Step 2: Understand Cross-Fertilization
Cross-fertilization, on the other hand, involves the fusion of gametes from two different individuals (biparental). This process increases genetic diversity as it combines genetic material from two parents.

### Step 3: Analyze the Differences
1. **Uniparental vs. Biparental**:
- Self-fertilization is indeed uniparental.
- Cross-fertilization is indeed biparental.
- **This statement is correct.**

2. **Gamete Fusion**:
- In self-fertilization, the male and female gametes come from the same parent.
- In cross-fertilization, the gametes come from different parents.
- **This statement is correct.**

3. **Examples of Organisms**:
- The examples given for self-fertilization are Ferritima and Periplaneta.
- The examples given for cross-fertilization are Tinea and Rana Tigrina.
- **This statement is incorrect.** Ferritima (earthworm) and Periplaneta (cockroach) do not self-fertilize; they reproduce through cross-fertilization. Tinea (a genus of tapeworms) and Rana Tigrina (Indian bullfrog) are examples of organisms that can self-fertilize and cross-fertilize, respectively.

4. **None of the Above**:
- This option suggests that none of the differences listed are wrong, which is incorrect since we have identified a wrong difference.
- **This statement is also incorrect.**

### Conclusion
The wrong difference is in the third statement regarding the examples of organisms. The examples provided for self-fertilization and cross-fertilization are not accurate.

### Final Answer
The wrong difference is the third statement about the examples of self-fertilization and cross-fertilization.
