false
true
The Correct Answer is False
Cleavage is a series of rapid mitotic divisions of a fertilized egg (zygote) that results in daughter cells (blastomeres) with the same number of chromosomes as the parent cell. However, if the context was about meiosis, then the statement would be accurate. Since the question does not specify meiosis, this is true for cleavage in general.
