WebProphase I (Stage 2) The DNA starts to coil itself up into visible chromosomes. The copies of each chromosome (sister chromatids) are connected together by a centromere. During the end of this stage the nuclear membrane starts to dissolve, centrosomes move towards the poles, and spindle fibers start to form. Crossing over occurs during this stage. WebMeiosis 1 Includes prophase 1, metaphase 1, anaphase 1, telophase 1. The result is 2 genetically different haploid cells. homologous pairs pull apart here Meiosis 2 Includes prophase 2, metaphase 2, anaphase 2, telophase 2. The result is 4 genetically different haploid cells. Individual chromatids pull apart here Sexual reproduction
