Now, those eukaryotic cells that divide via meiosis are known as gametocides. So gametocides divide via meiosis, and somatic cells divide via mitosis. Now, both of these processes are a type of cell division. The question is, what exactly is the major difference between mitosis and meiosis? So in mitosis, our somatic cell divides into two genetically identical cells that are diploid. And that means the chromosome number does not actually change.
