Here's why:

* Meiosis I: Starts with one diploid cell (containing two sets of chromosomes) and divides into two haploid cells (containing one set of chromosomes).

* Meiosis II: Each of the two haploid cells from meiosis I then divides again, resulting in a total of four haploid cells.

The type of cells produced depends on the organism and the starting cell:

* In humans: The four haploid cells produced at the end of meiosis II are sperm cells (in males) or egg cells (in females).

* In other organisms: The four haploid cells could be spores or other specialized cells depending on the organism's reproductive cycle.

In summary: Meiosis II results in four haploid cells, which are genetically distinct from the original diploid cell.
