A change in the amount of yolk and its distribution in the egg will affect:
Pattern of cleavage
Number of blastomeres produced
Fertilization
Formation of zygote
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
