Holoblastic and meroblastic cleavage are two types of cleavage patterns observed during early embryonic development, differing mainly in the extent of cytoplasm division. In holoblastic cleavage, the entire egg undergoes complete division. This type of cleavage is typical of eggs with little yolk, such as those of amphibians and mammals. The blastomeres formed are usually of equal size, and cleavage planes pass through the whole egg. An example of holoblastic cleavage is seen in the frog *Rana*
