The volume and distribution of yolk determine the cleavage pattern. The segmentation lines in holoblastic cleavage go all the way through the egg. Hence, it totally separates the egg. This kind of cleavage leaves a modest to scant amount of yolk in the egg. For instance, a frog or a human egg. The segmentation lines are restricted to a portion of the egg in meroblastic cleavage and do not completely penetrate the egg. Thus "Pattern of Cleavage" is the right answer
