WebDuring prophase I, differences from mitosis begin to appear. As in mitosis, the chromosomes begin to condense, but in meiosis I, they also pair up. Each chromosome carefully aligns with its homologue partner so that the two match up at corresponding positions along their full length. WebTHE BEHAVIOUR OF CHROMOSOMES DURING CELL DIVISION During mitosis. When the chromosomes condense during cell division, they have already undergone replication.
