cytokinesis

[kellym13]

Why do you suppose that cytokinesis generally occurs in the cell's midplane?

[MrMistery]

it doesn't always occur like that. In plants it is generally asimetric, to set up the poles.
If it occurs in the cell's midplane it is to make sure that both daughter cells end up having the same size and get the same cytoplasmic determinats(generally! because 2 daughter cells can have the same size and still get different cytoplasmic determinants.)

the position of metaphase DNA and mitotic spindle pose the cleavage furrow to the middle of the cells called midbody.
