Cleavage differ from mitosis in that:
Correct answer: D. It results in identical cells
- A. It occurs only in zygote
- B. It occurs in all body cells
- C. It results in haploid cells only
- D. It results in identical cells
Explanation
Cytokinesis during cleavage results in identical cells as the parent cell divides into two daughter cells. The other options are incorrect as cleavage is not limited to the zygote stage, does not occur in all body cells, and does not result in haploid cells.

About Embryonic Development
Embryonic development begins after fertilization with cleavage and formation of the morula and blastula, followed by gastrulation and the establishment of germ layers. It includes organ formation, tissue differentiation and early growth, rather than the later increase in size associated with postnatal development.
