How many cells are produced from the one parent cell in mitosis?

The answer is 2 daughter cells.

Mitosis is a kind of cell division that produces 2 daughter cells that are genetically identical to both the other daughter cell and the parent cell. Unlike meiosis, it only requires one division.

The parent cell first duplicates it's genetic material, then divide and leading to that both daughter cells has the exact same genetic material.

Mitosis is important in processes such as growth, repair etc. It ensures that you stay you. For example if you have brown eyes, you won't suddenly turn into blue eyes.
