Question

Quizplus · Accepted Answer

Cleavage on the surface of the yolk of the chicken egg is partial because the cytoplasm is only found in a small area at the periphery of the egg, while the majority of the egg is yolk. This type of cleavage is called meroblastic cleavage. Holoblastic cleavage is the type of cleavage that occurs in eggs that have evenly distributed yolk, such as those of amphibians. Isolecithal refers to egg cells that have a uniform distribution of yolk throughout the cytoplasm, and indeterminant refers to early embryonic development where individual cells have the potential to form an entire organism.
