synapsis.  when homologs come together in pairs and the arms of some of the chromatids overlap forming chiasma

homolog.  has 2 chromatids

Prophase	homolog chromosomes criss-cross at numerous locations (sing. chiasmata) chiasma holds the homologs together comprises 90 percent of the time needed for meiosis to take place
Metaphase	chromosomes arrange themselves (still paired) along the metaphase plate halfway between centrosomes spindle fibers begin to pull the homologs apart
Anaphase	sister chromatids remain attached 1 homologue of each pair move to a like centrosome
Telophase and Cytokinesis	cleavage furrows
