WebIn meiosis II, the chromosomes line up and sister chromatids are pulled to the opposite poles resulting in the formation of a total of four haploid cells. This pulling apart of sister chromatids is called disjunction and occurs during anaphase II of meiosis II. Thus the correct answer is option C. Solve any question of Cell Cycle And Cell ... Web1) Prophase I is the finest time to watch chiasmata develop during meiosis. This is due to the fact that chiasmata are created during the crossing over process, which takes place during prophase I of meiosis. In this phase, homologous chromosomes join up and cross over to exchange genetic material, leading to the development of chiasmata.
