Detailed explanation-1: -Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase. A key difference, however, is that during meiosis, each of these phases occurs twice-once during the first round of division, called meiosis I, and again during the second round of division, called meiosis II .

Detailed explanation-2: -The Phases of Meiosis II Meiosis II is known as equational division, as the cells begin as haploid cells and end as haploid cells. There are again four phases in meiosis II: these differ slightly from those in meiosis I.

Detailed explanation-3: -Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. During prophase II, the chromosomes condense, and a new set of spindle fibers forms. The chromosomes begin moving toward the equator of the cell.

Detailed explanation-4: -During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes, each with one copy of each chromosome. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes.

Detailed explanation-5: -Telophase II is the stage in meiosis II that follows after anaphase II. In anaphase II, the sister chromatids that were formerly joined at the centromere are separated from each other and moved away to opposite poles. At this point, the sister chromatids are sometimes referred to as sister chromosomes.
