Understand that mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell.
Recall that before mitosis begins, each chromosome in the parent cell is replicated during the S phase of the cell cycle, resulting in two sister chromatids for each chromosome.
During mitosis, specifically in the anaphase stage, the sister chromatids are separated and pulled to opposite poles of the cell.
As the cell completes mitosis and cytokinesis, each new nucleus receives one chromatid from each pair, which is equivalent to one complete set of chromosomes.
Since each chromatid is a copy of the original chromosome, each new nucleus ends up with two copies of each chromosome, one from each chromatid pair.
