leptotene : homologus pairing is formed and chromosomes start to get closer to each other.
zygotene: synapsis is formed between homologus chromosomes which is apoint oattachment.
pachytene:crosing over occer that homologus chromosomes exchange THIER GENETIC METERIALS.
DIPLOTENE: chiasmata formation disapear which was formed in pachytene.
diakinasis:homologus chromosomes start to seperate from each other.
