Question
During cleavage, what is the primary cellular characteristic observed?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Cleavage divisions are very rapid mitotic divisions where the cytoplasm of the large zygote is partitioned into smaller and smaller cells (blastomeres). There is no growth phase (G1 or G2) between these divisions, so the overall embryo size does not increase.
Hint
The cells get smaller but more numerous.
