Meiosis II is the second cell division event in meiosis. It resembles mitosis, but results in four haploid gametes, rather than two daughter cells. Clicking on each of the

Meiosis II follows Meiosis I, and while the process is similar to mitosis, the results are genetically different. The first stage of Meiosis II is prophase II. Here the chromosomes condense once again, while the nuclear membrane breaks down and a spindle apparatus begins to form in each of the daughter cells.
Next comes metphase II. During this stage the spindle fibers attach to the kinetchores of each sister chromatid, and the chromosomes align at the equator of each cell. The alignment of the sister chromatids is completely random.
This is followed by anaphase II, where the cells elongate and the sister chromatids are finally separated and pulled to opposite ends of the cells. The sister chromatids are now considered chromosomes.
Finally, during telophase II, the chromsomes uncoil, new nuclear membranes form, the spindle fibers are broken down, and the cells are split once again during cytokinesis. This results in the formation of four new haploid cells called gametes. If a haploid male gamete and a haploid female gamete combine, they form a new diploid zygote which can go on to become an embryo.
