Miosis

Prophase 1 Miosis. 

Prophase 1 in Miosis is divided into 5 stages:

(1) Leptotene, which is the stage where duplicated chromosomes start to condense.

(2) Zygotene, this stage involves the bivalent forming and crossing over starts to occur.

(3) Pachytene, the synapsis is complete and therefore corssing over ocurs.

(4) Diplotene, Chiasma is now visible and the synaptonemal complex disappears. 

(5) Diakinesis, Bivalent is now ready for the next stage of miosis... Metaphase.
