WebCrossing over. The points where homologues cross over and exchange genetic material are chosen more or less at random, and they will be different in each cell … WebThe cell then divides. Telephase I occurs during meiosis I. Prophase II. Chromosomes condense, spindle fibers form in each new cell, and spindle fibers attach to chromosomes. Prophase II occures during meiosis II. Metaphase II. Centromeres of chromosomes line up randomly at the equator of each cell. Metaphase II occurs during meiosis II.
