IV. Examples of apomixis are Citrus and mango.

Options

A. I , III and IV
B. II, III and IV
C. I, II and III
D. I , II and IV

Answer

To solve the question regarding apomixis, we will analyze each statement provided and determine its validity based on the definition and characteristics of apomixis.

### Step-by-Step Solution:

1. **Understanding Apomixis**:
- Apomixis is a form of reproduction that allows for the production of seeds without fertilization. It is a type of asexual reproduction.

2. **Evaluating Statement I**:
- **Statement I**: "An apomixis is a form of sexual reproduction."
- This statement is **incorrect** because apomixis is not sexual reproduction; it is a form of asexual reproduction.

3. **Evaluating Statement II**:
- **Statement II**: "Apomixis is a mechanism to produce seeds without fertilization."
- This statement is **correct**. Apomixis indeed allows for seed formation without the need for fertilization.

4. **Evaluating Statement III**:
- **Statement III**: "Apomictic embryos are similar in their genetic nature."
- This statement is **correct**. The embryos produced through apomixis are clones of the maternal plant, meaning they have the same genetic makeup.

5. **Evaluating Statement IV**:
- **Statement IV**: "Examples of apomixis are Citrus and mango."
- This statement is **correct**. Both Citrus and mango are known to exhibit apomixis.

6. **Conclusion**:
- From the analysis, we find that:
- Statement I is false.
- Statements II, III, and IV are true.
- Therefore, the correct answer includes statements II, III, and IV.

### Final Answer:
