Assertion :-Each pair of chromosome segregete independently of another pair.
Reason :- Each gene pair also segregates independently of another pair.

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 "Each pair of chromosomes segregate independently of another pair." This is a reference to Mendel's Law of Independent Assortment, which indicates that the segregation of one pair of alleles does not influence the segregation of another pair during gamete formation.

2. **Understanding the Reason**: The reason given is "Each gene pair also segregates independently of another pair." This statement is generally true for genes located on different chromosomes or far apart on the same chromosome. However, it is not universally applicable because genes that are located close together on the same chromosome may be linked and do not assort independently.

3. **Evaluating the Truth of the Assertion**: The assertion is true. According to Mendel's principles, during meiosis, the alleles for different traits segregate independently of one another, provided the genes are on different chromosomes or sufficiently far apart on the same chromosome.

4. **Evaluating the Truth of the Reason**: The reason is false in a general context because it does not account for linked genes. Genes that are located close together on the same chromosome tend to be inherited together, violating the principle of independent assortment.

5. **Conclusion**: Since the assertion is true and the reason is false, the correct conclusion is that the assertion is true, but the reason is not a correct explanation of the assertion.

**Final Answer**: The assertion is true, but the reason is false.
