Usage: biology; embryology; technical
Examples
- Meroblastic cleavage occurs in bird and reptile eggs, where the yolk prevents complete cell division.

- In meroblastic embryos, the blastoderm forms only on the surface of the yolk.
- The meroblastic pattern of division is an adaptation to eggs with abundant nutritive material.
