Prophase I Homologous chromosomes pair up (synapsis). Crossing over (DNA exchange) occurs.	Metaphase I Homologous chromosomes align along center of cell (metaphase plate), the pairs oriented toward opposite poles of the cell.	Anaphase I Homologous chromosomes separate, moving to opposite poles. Sister chromatids are no longer identical: genetic recombination has occurred.	Telophase I/Cytokinesis I One set from the paired chromosomes arrives at each pole. The cell divides into two haploid cells.
