Assertion : The law of independent assortment can be studied by means of dihybrid cross
Reason : The law of independent assortment is applicable only to linked genes

Options

A. A and R both correct and R is correct explanation of A
B. A and R both are correct but R is not correct explanation of A
C. A is true but R is false
D. Both are false

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "The law of independent assortment can be studied by means of dihybrid cross."
- This is true because a dihybrid cross involves two traits, and according to Mendel's law of independent assortment, alleles for different traits segregate independently during gamete formation.

2. **Understanding the Reason**:
- The reason states that "The law of independent assortment is applicable only to linked genes."
- This statement is false. The law of independent assortment applies to genes that are located on different chromosomes or are far apart on the same chromosome. Linked genes, which are located close to each other on the same chromosome, do not assort independently; they tend to be inherited together.

3. **Conclusion**:
- Since the assertion is true and the reason is false, the correct conclusion is that the assertion is correct while the reason is incorrect.

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