Prophase I - crossing-over occurs between tetrads Metaphase I - Paired homologous chromosomes line up across the center of the cell Anaphase I - Spindle fibers pull each homologous chromosome pair toward an opposite end of the cell Telophase - A nuclear membrane forms around each cluster of chromosomes and cytokinesis follows, forming two new cells Prophase II - Chromosomes consist of two chromatids, but they do not pair to form tetrads Telophase II - A nuclear membrane forms around each ...
