Explanation / Answer

Prophae I - Chromosomes begin to condense - The synaptonemal complex aligns homologs into tetrads - Crossing over occurs, during which nonsister chromatids exchange DNA - Homologs are connected by chiasmata as the synaptonemal complex begins to separate - Chromosomes condense further as chiasmata become more visible during separation - Metaphase I
