WebA study of chromosome structure and behavior at mitosis and meiosis has been made in order to compare the two types of divisions and to aid in the analysis of the mechanism … 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.
