The main events in meiosis During the first division, chromosomes pair and sections of are exchanged between non-sister chromatids as a result of crossing over (prophase I). The nuclear membrane fragments and pairs of homologous chromosomes become aligned on the . One chromosome of each pair is lined up on either side of the equator (metaphase I). The pairs of chromosomes are separated and pulled apart (anaphase I) to either pole to form the first two daughter nuclei (telophase I). divides the cytoplasm and each daughter cell now contains the number of chromosomes. During the second division, the nuclear membrane fragments and individual chromosomes composed of 2 sister become aligned on the equator of the spindle (metaphase II). The pairs of chromatids are separated and pulled apart (anaphase II) to either to form daughter nuclei as the nuclear membranes reform around the new nuclei (telophase II). Cytokinesis divides the two cells into fou
