Meroblastic Cleavage

Cleavage pattern observed in the telolecithal eggs of reptiles and birds, in which cleavage is restricted to a small disc of cytoplasm at the animal pole. Compare with holoblastic cleavage.

Cleavage Pattern

The division of cells in the early embryo, determining the spatial arrangement of cells in the resulting organism.
