- This cell division produces two genetically identical cells
- Each new cell contains the same number of chromosomes as the original cell.
- Needed to make new cells for growth of the body
- Needed to make new cells to replace those that have been damaged
- Make new cells to replace those that have worn out
- New cells are genetically identical to mother cell
- This cell division produces two genetically identical cells
- Meiosis
- This cell division produces 4 genetically different gametes (sperm or eggs)
- Contains half the normal number of chromosomes
- New cells genetically different to mother cell
- This cell division produces 4 genetically different gametes (sperm or eggs)
