Web♦ Meiosis can be divided in two stages: meiosis I and meiosis II. It is in the prophase of meiosis I that crossing over of the chromosomes takes place, and the homologous chromosomes are separated into two daughter cells. In meiosis II, the sister chromatids are pulled apart from each other to give rise to four haploid daughter cells.

WebJun 8, 2024 · During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
