"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. So you're still stuck within that zona pellucida. So we'll draw it in here. " - Cleavage formation

WebStep 1: a zygote is the single cell formed when an egg and a sperm cell fuse; the fusion is known as fertilization. Step 2: the first 12-to 24-hours after a zygote is formed are spent in cleavage – very rapid cell division.

WebTopic: Embryogenesis. The early stages of embryonic development, such as fertilization, cleavage, blastula formation, gastrulation, and neurulation, are crucial for ensuring the fitness of the organism. Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm each contain one set of chromosomes.

WebThe early stages of embryonic development begin with fertilization. The process of fertilization is tightly controlled to ensure that only one sperm fuses with one egg. After fertilization, the zygote undergoes cleavage to form the blastula.
