Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Meiosis-I is called reductional division in which crossing over occurs between homologous chromosomes and as end product each cell receives one set of chromosomes.
The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes. Therefore, each cell has half the number of sister chromatids to separate out as a diploid cell undergoing mitosis.
Hence the correct answer is (B)
