Incomplete cleavage is when the cells don't completely separate into blastomeres.


Also known as meroblastic cleavage, this happens when either the cleavage furrows don't penetrate the yolk (discoidal cleavage) or when cytokinesis does not happen (superficial cleavage) and the embryo is a blastodisc sitting on top of the yolk, which is still intact.
