WebJul 17, 2024 · Ed Reschke/Photolibrary/Getty Images. In telophase I of meiosis, the following events occur: The spindle fibers continue to move the homologous chromosomes to the poles.; Once movement is complete, each pole has a haploid number of chromosomes.; In most cases, cytokinesis (the division of the cytoplasm) occurs at the same time as … WebDuring metaphase, the mitotic spindle uses the spindle fibers within it and captures the chromosomes. After the chromosomes have been linked to the mitotic spindle by the spindle fibers, the mitotic spindle pulls on these chromosomes and moves them towards the center of the cell into a region referred to as the metaphase plate.
