meroblastic
(adjective)
undergoing only partial cleavage
Examples of meroblastic in the following topics:
-
Cleavage, the Blastula Stage, and Gastrulation
- Cleavage can take place in two ways: holoblastic (total) cleavage or meroblastic (partial) cleavage.
- Other species, such as birds, with a lot of yolk in the egg to nourish the embryo during development, undergo meroblastic cleavage.
-
Cleavage of the Zygote
- Depending mostly on the amount of yolk in the egg, the cleavage can be holoblastic (total) or meroblastic (partial).
- On the other hand, meroblastic cleavage occurs in animals whose eggs have more yolk, such as birds and oviparous reptiles (although some viviparous reptiles also exist).
