Detailed explanation-1: -Meiosis-I is similar to Mitosis and so it is called Meiotic Mitosis.

Detailed explanation-2: -Meiosis II is the second division of meiosis. It occurs in both of the newly formed daughter cells simultaneously. Meiosis II is similar to Mitosis in that the sister chromatids are separated.

Detailed explanation-3: -Meiosis II is similar to mitosis. However, there is no “S” phase. The chromatids of each chromosome are no longer identical because of recombination. Meiosis II separates the chromatids producing two daughter cells each with 23 chromosomes (haploid), and each chromosome has only one chromatid.

Detailed explanation-4: -Meiosis I and II are similar in some aspects, including the number and arrangement of their phases and the production of two cells from a single cell. However, they also differ greatly, with meiosis I being reductive division and meiosis II being equational division. In this way, meiosis II is more similar to mitosis.

Detailed explanation-5: -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.
