Incompete cleavage

Definition
noun
(embryology) The partial cleavage in telolecithal or megalecithal eggs in certain animals, such as birds and reptiles.
Supplement
Depending mostly on the amount of yolk in the egg, cleavage can be holoblastic (complete or total) or meroblastic (incomplete or partial).
In meroblastic cleavage, only a portion of the egg divides. This is because of the large amount of yolk in the egg cell that the cleavage furrows do not penetrate the yolk.
Two major types of meroblastic cleavage:

Synonyms:

  • meroblastic cleavage
  • partial cleavage
  • Compare: holoblastic cleavage
