Eukaryotic cells can divide by either one of two methods. If we're talking about somatic eukaryotic cells, then those divide via mitosis. If we're talking about gametocides, those divide via meiosis. Now, mitosis is the process by which a somatic cell divides into two genetically identical deployed daughter cells cells, and the chromosome number remains exactly the same. So if we begin with 46 chromosomes in a human somatic cell, we produce 46 chromosomes in the daughter cell, and this is mitosis. Now, in meiosis, we basically have a single gametocide, divides into four genetically different haploid cells.
