Mitosis and Meiosis Comparison

 Mitosis produces 2 cells while meiosis produces 4.
The cells produced in mitosis are identical to the parent while those in meiosis are not.
 There are 4 phases in mitosis: prophase, metaphase, anaphase, and telophase. However, meiosis has 8 because each phase happens twice.
Crossing over only occurs in prophase 1 of meiosis. Chromosome pairs only line up in meiosis 1. During mitosis and during meiosis 2 (which is exactly like mitosis), chromosomes line up singly. Meiosis produces haploid gametes (sex cells with half the number of chromosomes) while mitosis produces identical cells with the diploid number or full number of chromosomes.
 Mitosis has 1 divison while meiosis has 2.

 Mitosis and meiosis are similar in that they are both types of cell divisions. Mitosis and meiosis 2 are exactly the same.
