Assertion :- In human genetic, pedigree study provides a strong tool, which is utilized to trace the inheritance of a specific trait, abnormality or disease.
Reason :- The controlled crosses that can be perfoemed in pea plant or same other organism, are not possible in case of human beings.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

To analyze the assertion and reason provided in the question, we will break down each statement and evaluate their correctness and relationship.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that in human genetics, pedigree study is a strong tool used to trace the inheritance of specific traits, abnormalities, or diseases.
- **Evaluation**: This statement is true. Pedigree analysis is indeed a crucial method in human genetics that helps track the inheritance patterns of traits across generations in families.

2. **Understanding the Reason**:
- The reason states that controlled crosses, which can be performed in pea plants or other organisms, are not possible in humans.
- **Evaluation**: This statement is also true. In organisms like pea plants, controlled breeding experiments can be conducted to study inheritance patterns. However, in humans, ethical and practical constraints prevent such controlled breeding experiments.

3. **Relationship Between Assertion and Reason**:
- The assertion is about the utility of pedigree studies in tracing inheritance in humans, while the reason explains why such studies are necessary—because controlled breeding experiments are not feasible in humans.
- **Evaluation**: The reason provides a valid explanation for the assertion, as it highlights the limitations in human genetics that make pedigree analysis a necessary tool.

4. **Conclusion**:
- Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason is a correct explanation of the assertion.

### Final Answer:
Both the assertion and reason are true, and the reason is a correct explanation of the assertion.
