The cell divisions do not completely divide the egg, so this type of cleavage is called meroblastic (Greek, meros, “part”). WebThe blastodisc, also called the germinal disc, is the embryo-forming part on the yolk of the egg of an animal that undergoes discoidal meroblastic cleavage. Discoidal cleavage occurs in those animals with a large proportion of yolk in their eggs, and include insects , fish , reptiles and birds . [2]
