It may be radially symmetrical, bilaterally, symmetrical, spirally symmetrical or irregular. Unequal: When the resultant blastomeres become unequal in size. b. Meroblastic cleavage: WebSo you're finished with the cleavage stage of early embryogenesis. You've gone from one cell and just divided, without growing at all, into two, four, eight, sixteen and then thirty-two cells. And now more interesting things start to happen.
