Meiosis is a key event of the sexual cycle in Eukaryotes. It is the stage of the life cycle when a cell gives rise to two haploid cells (gametes) each having half as many chromosomes. Two such haploid gametes, arising from different individual organisms, fuse by the process of fertilization, thus completing the sexual cycle. Meiosis is ubiquitous among eukaryotes.
Prokaryotes, such as bacteria, do not have a nuclear membrane surrounding their cellular DNA, so cell division is happens differently than in eukaryotes. Even though the cell does not undergo mitosis, the end result is the same.
