Here's why:

* Meiosis is a specialized type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell.

* Gametes are essential for sexual reproduction.

* The reproductive system is responsible for producing and delivering gametes.

While meiosis itself happens within specific cells (sperm cells in the testes and egg cells in the ovaries), the entire process is overseen and regulated by the reproductive system.
