The difference in the number of chromosomes between a parent cell and its daughter cells depends on the type of cell division:

1. Mitosis:

* Parent cell: Has a diploid number of chromosomes, meaning two sets of chromosomes (represented as 2n).

* Daughter cells: Also have a diploid number of chromosomes (2n).

* Difference: None. The daughter cells are genetically identical to the parent cell.

2. Meiosis:

* Parent cell: Has a diploid number of chromosomes (2n).

* Daughter cells: Have a haploid number of chromosomes, meaning only one set of chromosomes (represented as n).

* Difference: Daughter cells have half the number of chromosomes as the parent cell.

In summary:

* Mitosis: Parent cell (2n) → Daughter cells (2n)

* Meiosis: Parent cell (2n) → Daughter cells (n)

Example:

* Human cells have 46 chromosomes (2n). In mitosis, the daughter cells will also have 46 chromosomes.

* In meiosis, the daughter cells (sperm and egg cells) will have 23 chromosomes (n).
