Here's why:

* Meiosis I: The replicated chromosomes are then separated into two daughter cells, each receiving one copy of each chromosome (homologous pair).

* Meiosis II: The sister chromatids of each chromosome are then separated, resulting in four haploid daughter cells.

It's important to remember that DNA replication only occurs once during the entire meiotic process. This ensures that the resulting gametes (sperm or egg cells) have half the number of chromosomes as the original cell.
