Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Genetic variation is an important force in evolution because it allows natural selection to increase or decrease the frequency of alleles already in the population. Meiosis increases genetic variability as it leads to recombination due to crossing over between non-siter chromatids during gametogenesis.
So, the correct option is 'Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion'.
