| Mitosis | Meiosis |
| Makes 2 cells | Makes 4 cells |
| Makes 2n (diploid) cells | Makes 1n (haploid) cells |
| Makes other body cells besides sperm or eggs | Makes gametes (sperm & eggs) |
| Divides once | Divides twice BUT copies DNA once |
| Makes cells identical to parent & each other | Makes cells different from parent & from each other |
| Used for growth, repair of injuries, replacement of worn out cells | Used for sexual reproduction |
| No synapsis | Synapsis happens during prophase I |
| No crossing over | Crossing over happens during prophase I |
| No independent assortment | Independent assortment during Anaphase I |
| Copies DNA every time it divides | Copies DNA during Interphase I but NOT skips Interphase II |
