Here's why:
* Meiosis I: A single diploid cell (with 2n chromosomes) divides into two haploid cells (with n chromosomes).
* Meiosis II: Each of these haploid cells then divides again, producing a total of four haploid cells.
Therefore, the n value for the cells produced by meiosis is n, meaning they contain half the number of chromosomes as the original cell.
