Meiosis is two successive nuclear divisions. I Mitosis Prophase Synapsis occurs forms tetrads. Crossing over occurs. Neither synapsis nor crossing over occurs. Metaphase Homologous pairs align on the metaphse plate.
Individual chromosomes align on the metaphase plate.
I separates pairs of chromosomes. Centromeres do NOT divide and sister chromatids stay together, move to same pole of cell. Mitosis separates sister chromatids of individual chromosomes.
