OverviewIntroductionPhases of meiosisMeiosis IMeiosis IIHow meiosis "mixes and matches" genesBefore entering meiosis I, a cell must first go through interphase. As in mitosis, the cell grows d…During 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.For instance, in the image below, the letters A, B, and C represent genes found at particular spo…This process, in which homologous chromosomes trade parts, is called crossing over. It's helped along by a protein structure called the synaptonemal complex that holds the homologues together.
