WebFeb 2, 2024 · The unipotent stem cells that can divide and produce gametes are called germ cells. The gametes of haploid sex cells are produced by a germ cell, which undergoes meiotic cell division and produces genetically unique gametes. These gametes fuse during fertilization and form diploid zygotes. Webcell division produces identical diploid daughter cells. Meiotic cell division creates unique haploid daughter cells called gametes or sex cells. In humans, meiotic cell division occurs only in germ-line cells in the testes and ovaries, while mitotic cell division occurs in somatic cells and produces identical somatic cells.
