Meosis

So we got MITOsis, which is the asexual reproduction of cells in plants.  But then theres MEOsis.  Meosis is the sexual reproduction of organisms' cells.  When meosis takes place, there are a couple more stages that take place which differ from the mitosis process.  For one there is no S phase in meosis.  And there are 2 phases of metaphase, and anaphase.  Before meosis can take place, the chromosomes (all 46 of em) must be assambled.  Then it can begin to divide.  Meosis requires even numbers of chromosomes to begin.  Then they turn into bivalents.  Then the bivalents divide from oposite poles and seperate.  Then telophase as usual, and eventual complete division of the cell. 


PS.  i'm pretty glad i did this post cause if i wouldn't of done at least this much on the subject, i would be completly lost.  It's comin' back to me now though, its all comin' back to me.
