Prophase I The chromosomes condense, and the nuclear envelope breaks down. crossing-over occurs.Metaphase IPairs of homologous chromosomes move to the equator of the cell.Anaphase IHomologous chrmosomes move to the oppisite poles of the cell.Telophase I and CytokinesisChromosomes gather at the poles of the cells. the cytoplasm divides.Prophase IIA new spidle forms around the chromosomes.Metaphase IIChromosomes line up at the equator.Anaphase IICentromeres divides. chromatids move to the opposite poles of the cells.Telophase II and CytokinesisA nuclear envelope forms around each set of chromosomes. the cytoplasm divides.
