Telolecithal
Telolecithal (Greek: τέλος (telos) = end, λέκιθος (lekithos) = yolk), also known as macrolecithal, refers to the uneven distribution of yolk in the cytoplasm of ovums found in birds, reptiles, fish, and monotremes. The yolk is concentrated at one pole of the egg separate from the developing embryo.
This type of egg undergoes discoidal meroblastic cleavage, where yolk is not incorporated in the cells during cell division.
