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 good for the genes that are located closely on the same chromosome.Reason (R): Closely located genes assort independently.Choose the correct answer from the options given below:

  1. A
    Both (A) and (R) are correct and (R) is the correct explanation of (A)
  2. B
    Both (A) and (R) are correct but (R) is not the correct explanation of (A)
  3. C
    (A) is correct but (R) is not correct
  4. D
    (A) is not correct but (R) is correct

Solution & Step-by-step Explanation

1. Assertion is correct: Genes located close together on the same chromosome are "linked" and tend to be inherited together, violating the law of independent assortment.2. Reason is incorrect: Closely located genes do not assort independently; they show linkage. Only genes on different chromosomes or very far apart on the same chromosome assort independently.
