Mitosis

Starts with one human cell containing 46 chromosomes

Ends up with 

2 cells each containing 46 chromosomes

 

When growth or replacement cells are required for the body, mitosis occurs. The chromosomes copy themselves and then attach themselves to the original.

Mitosis is when the cells divide creating a direct copy for growth and maintenance

 All these chromosomes then line themselves up and split down the middle to form a duplicate of each other as the cell divides.

Simplified, mitosis in a nucleus with just four chromosomes would be as follows:

Mitosis produces 2 identical cells

Mitosis produces two identical cells.
