Select the correct statement about meroblastic cleavage.

Only a part of the egg undergoes cleavage in meroblastic cleavage.

In meroblastic cleavage, only a portion of the egg undergoes division, typically due to the presence of a significant amount of yolk or other nutritive materials. Cleavage occurs in the cytoplasmic region surrounding the yolk-rich area, while the yolk itself remains undivided. This type of cleavage is common in telolecithal and centrolecithal eggs, where yolk is concentrated at one end or in the center, respectively.
