  • Cell Wars An explanation of Meiosis. Light sabers represent chromosomes, In Leptotene the jedi appear, in zygotene they approach each other, in Pachytene the light sabers clash and the tips swap representing crossing over, in Diplotine the light sabers pull apart, in Diakinesis the jedi spread apart, In Metaphase 1 the jedi line up and in Anaphase 1 they are pulled apart. Telophase and interkenisis were represented by resting and splitting apart, Metaphase 2 is where the jedi line up again (this time with 4), anaphase 2- they get pulled apart and in telophase 2 all 4 split up
