What happens after fertilization?


Fertilization results in the creation of a zygote. The zygote begins the process of cleavage or cellular replication, resulting in a morula or ball of cells. At 3 days post-conception a solid ball of 16 cells is present. This blastomere begins to separate into two parts: the trophoblast or outer layer of cells, which will form the placenta, and an inner cell mass or embryoblast, which will begin to differentiate and evolve into the embryo, and a cavity forms within the cell mass.
