differences :
1. mitosis happens in all of the cells in the body but meiosis is just for making gametes
2. the number of chromosomes will be changed to half in meiosis
but in mitosis it won't change
3-( not completely sure about this one)
I heard before that meiosis happens in 2 steps (meiosis l and meiosis ll)
but mitosis happens in only 1 step
similarities
1 in both of them, the cell is separated into two cells
2. they both happen in the cells
hope this helps
good luck
