1 – Mitosis produces genetically identical cells. So it cannot introduce variation. This is wrong.
2 – Meiosis introduces variation in species. It cannot produce genetically identical cells. This is wrong.
3 – In mitosis, the 2 daughter cells produced are diploid. So this is correct
4 – In meiosis, the 4 daughter cells produced are haploid. So this is correct.
5 – Mitosis only produces 2 daughter cells. This is correct.
