- Initial divisions of zygote to form the multicellular embryo
-
During cleavage the cells are called "Blastomeres"
-
They are special mitotic divisions
-
Since they are mitotic divisions, they maintain the 2N complement
-
They are rapid cell divisions with no intervening G1 & G2 phases
-
Cells become smaller with time
-
Holoblastic Cleavage: cells are completely separate
