Chromosomes H Synapsis Stages Prophase1 Meiosis 1)leptotene Start

Front Stages of Prophase1 in Meiosis:
Back 1)Leptotene
Chromosomes start to condense, H. chromosomes move closer, "Nucleus size increases."

2)Zygotene
Synapsis begins ie "Synaptonemal Complex" starts to form.

3)Pachytene
Synapsis is completed, Chiasmata formation, Crossing over occurs.

4)Diplotene
H. chromosomes begin to separate, connected only through Chiasma/chiasmata

5)Diakinesis
Condensation is complete, separation of pairs is complete (united at just one point), Nuceloli disappear.
