Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Mendel’s law of Independent assortment does not hold goods for the genes that are located closely on the same chromosome.
Reason (R): Closely located genes assort independently.
Answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Independent Assortment states that alleles of different genes distribute into gametes independently. This only applies to genes on different chromosomes or genes far apart on the same chromosome.
Detailed Explanation:
- Assertion (A): Genes located very close to each other on the same chromosome are linked. They tend to be inherited together and do not follow Mendel's law of independent assortment. This statement is correct.
- Reason (R): Closely located genes exhibit linkage and do not assort independently. Independent assortment is the result of genes being on different chromosomes or very far apart. This statement is incorrect.
Step 2: Final Answer:
The assertion is a fact of genetics, but the reason provided is scientifically wrong.
