Which of these is NOT a function of mitosis?

Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell called daughter cells. In multicellular organisms, mitosis produces more cells for growth and repair.
Meiosis produces haploid gametes (ova or sperm) that contain one set of 23 chromosomes because they divide twice during the process.
