Abstract
THERE has been widespread acceptance of the generalization formulated by Conklin1 and Wilson2 that, when mitosis is followed by normal cytokinesis in plants and animals, the “cleavage takes place in a plane approximately at right angles to the spindle axis and primarily across its equatorial plane”2. (In certain cells which are large in comparison with the mitotic apparatus, the equator of the spindle becomes a part of the cleavage surface, but the latter may curve on either side of the spindle.) The generalization has been shown to be true for all cases of cytokinesis which have been studied intensively3. Moreover, after the nucleus has been displaced by experimental means, the subsequent cleavage has occurred through the middle of the spindle wherever the spindle might be at the late anaphase stage1,4–8.
