* Cleavage divisions continue and the 4-celled Embryo gives rise to an 8-celled Embryo.
* Cleavage divisions continue and the 4-celled Embryo gives rise to an 8-celled Embryo.
* These cells are totipotent and divide asynchronously.
* After the 8-celled stage, a ball of cells is formed. This stage is referred to as a '''Morula'''.
