Multicellular eukaryotes and single-celled sex cells reproduce by a process called meiosis. In this process, the number of chromosomes in a mother cell is halved to produce gametes, cells that fuse with other cells. This happens in plants, animals, and fungi. German biologist, Oscar Hertwig first discovered meiosis in sea urchin eggs in 1876.
