DNA replication occurs in the S phase. After that is G2, which is growth and final preparations for division. Chromosomes are checked for errors and repairs are made if needed. Essentially, the cell prepares for division.
At the end of cytokinesis there no longer exists chromatids, they are just individual chromosomes.
If you're talking about Meiosis, there are 4 (HAPLOID) daughter cells produced at the end of meiosis. So each daughter cell will have HALF the number of chromosomes as the mother cell.
Whereas at the end of Mitosis there are 2 identical DIPLOID sister cells.

Answer:
Cell differentiation
Explanation:
Cell differentiation is common with multicellular organisms. It is the process by which a cell changes from one cell form to another. Cell differentiation makes the change from a zygote to a complex system with different parts.Cells which have been differentiated also becomes specialized. Complex multicellular animals and plants would not be in existence without specialization. This is because cells have specialized functions and each cell is very important to the survival of the organism.
