Read the all statements carefully :
(i) Mendel conducted artificial pollination/cross pollination experiments using several true breeding pea line
(ii) True breeding having underogone continuous self pollination, show stable trait inheritance
(iii) Mendel selected 14 true breeding pea plant varieties.

Options

A. Only i and iii are correct
B. i, ii and ii are correct
C. Only iii is incorrect
D. i and ii are incorrect

Answer

To analyze the statements regarding Mendel's experiments with pea plants, we will evaluate each statement step by step.

### Step-by-Step Solution:

1. **Understanding True Breeding**:
- True breeding refers to organisms that, when self-pollinated, produce offspring that are identical to themselves. This means the alleles for the traits are homozygous (either both dominant or both recessive).
- **Hint**: Remember that true breeding plants have consistent traits across generations.

2. **Evaluating Statement (i)**:
- The first statement claims that Mendel conducted artificial pollination or cross-pollination experiments using several true breeding pea lines. This is correct. Mendel crossed different true breeding varieties to study inheritance patterns.
- **Hint**: Cross-pollination is essential for studying the inheritance of traits in genetics.

3. **Evaluating Statement (ii)**:
- The second statement states that true breeding plants, having undergone continuous self-pollination, show stable trait inheritance. This is also correct. Continuous self-pollination of true breeding plants results in offspring that consistently exhibit the same traits.
- **Hint**: Self-pollination leads to uniformity in traits due to the homozygous nature of the alleles.

4. **Evaluating Statement (iii)**:
- The third statement mentions that Mendel selected 14 true breeding pea plant varieties. This is correct. Mendel used 14 varieties to observe different traits, such as plant height, flower color, and pod shape.
- **Hint**: Mendel's selection of multiple varieties was crucial for his experiments to analyze various traits.

5. **Conclusion**:
- All three statements (i), (ii), and (iii) are correct. Mendel's work with true breeding pea plants laid the foundation for the principles of inheritance in genetics.

### Final Answer:
All three statements are correct.
