prophase I- centromeres align and spindles attach to chromosomes, crossing over occurs
metaphase I- chromosome tetrad line up in center of cell
anaphase I- chromosome pairs separate and move to poles of cell
telophase- cleavage furrow forms, spindles disappear
cytokinesis I- cell splits into 2 diploid cells
prophase II- centromeres align again, spindles attach to chromosome
metaphase II- chromosome align in center
anaphase II- chromatids split apart and move to poles of cell
telophase II- individual chromatids move away from each other, nuclear envelope appears
cytokinesis II- each cell splits into 2, leaving the result as 4 haploid gametes
