Vedclass · Answer

(C) Cleavage is a series of rapid mitotic divisions of the zygote that occur without any intervening growth phases ($G_1$ and $G_2$ phases). In normal mitosis,cells undergo growth phases to increase their size and mass before dividing. In contrast,during cleavage,the total volume of the embryo remains constant while the number of cells (blastomeres) increases,meaning the cells become progressively smaller with each division.

Cleavage divisions differ from normal mitotic divisions in that
