Assertion: Mendelian disorders are transmitted to offspring on the same lines as in the principles of inheritance.
Reason: The pattern of inheritance of Mendelian disorders cannot be traced in a family by the pedigree analysis.

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

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that Mendelian disorders are transmitted to offspring according to the principles of inheritance. This is true because Mendelian inheritance follows specific patterns, such as dominant and recessive traits. For example, if one parent has a dominant trait (represented by a capital letter) and the other has a recessive trait (represented by a lowercase letter), the offspring can inherit these traits in predictable ways.

2. **Understanding the Reason:**
- The reason given claims that the pattern of inheritance of Mendelian disorders cannot be traced in a family by pedigree analysis. This statement is false. Pedigree analysis is a method used to trace the inheritance of traits and disorders through generations in a family. It allows geneticists to visualize how traits are passed down and to identify carriers of Mendelian disorders.

3. **Evaluating the Relationship Between Assertion and Reason:**
- Since the assertion is true (Mendelian disorders are indeed transmitted according to the principles of inheritance), and the reason is false (the pattern of inheritance can be traced using pedigree analysis), we conclude that the assertion stands independently of the reason.

4. **Conclusion:**
- The correct evaluation of the statements is that the assertion is true, while the reason is false. Therefore, the answer to the question is that the assertion is true, but the reason is not a correct explanation of the assertion.

**Final Answer:**
- Assertion is true, but the reason is false.
