Choose the correct statements. In relation to gametes
(I) They may be produced from either haploid or diploid parents
(II) They are produced by meiosis only
(III) They can be produced by mitosis
(IV) They can be produced by mitosis (or) meiosis

Options

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

Answer

To solve the question about the statements related to gametes, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement I: They may be produced from either haploid or diploid parents.**
- **Analysis**: This statement is correct. Gametes can be produced from both haploid and diploid organisms. For example, in honey bees, the female is diploid and produces gametes through meiosis, while the male is haploid and can produce gametes through mitosis.
- **Conclusion**: This statement is **true**.

2. **Statement II: They are produced by meiosis only.**
- **Analysis**: This statement is incorrect. While gametes are typically produced by meiosis, they can also be produced by mitosis in certain organisms, such as the male honey bee. Therefore, saying they are produced by meiosis only is misleading.
- **Conclusion**: This statement is **false**.

3. **Statement III: They can be produced by mitosis.**
- **Analysis**: This statement is correct. As mentioned earlier, gametes can be produced by mitosis in some organisms. For example, male honey bees produce gametes through mitosis.
- **Conclusion**: This statement is **true**.

4. **Statement IV: They can be produced by mitosis (or) meiosis.**
- **Analysis**: This statement is also correct. Gametes can indeed be produced by either mitosis or meiosis, depending on the organism and the type of gamete being produced.
- **Conclusion**: This statement is **true**.

### Final Evaluation:
Based on the analysis:
- Statement I is true.
- Statement II is false.
- Statement III is true.
- Statement IV is true.

Thus, the correct statements are I, III, and IV.

### Answer:
The correct answer is **C: 1, 3, and 4**.
