Answer: The daughter cells develop after the cell division will have unequal number of chromosomes.
Explanation:
The interphase is the stage of the cell cycle in which the parent cell prepares itself for division. It increases in size and develops organelles for cell division. Before the cell division the replication of the genetic material in the form of DNA is necessary so that both daughter cells receive equal amount of genetic material after the cell splits by mitosis. Mitosis is a cell division in which the parent diploid cell splits into two haploid daughter cells. Each daughter cell receives the half the chromosomes as that of the parent cell.
