The process of cell division that produces copies of cells with 46 chromosomes is called mitosis.

Here's why:

* Mitosis is the process of cell division that creates two identical daughter cells from a single parent cell.

* Humans have 46 chromosomes, arranged in 23 pairs.

* Mitosis ensures that each daughter cell receives a complete set of 46 chromosomes (one from each pair).
