Here's why:
* Meiosis is a specialized type of cell division that reduces the number of chromosomes in a cell by half. This is essential for sexual reproduction because it ensures that the offspring receive one set of chromosomes from each parent.
* Mitosis, on the other hand, is a type of cell division that produces two identical daughter cells. It's used for growth, repair, and development, but not for the formation of gametes.
Therefore, meiosis is the unique process that happens only during the formation of gametes (sperm and egg cells).
