Full Answer

Meiosis refers to eukaryotic cell division, which constructs gametes or sex cells from diploid cells. A gamete contains one copy of every chromosome. Two copies of every chromosome are in a diploid cell.

Both of them can be further divided into prophase, metaphase, anaphase and telophase stages. Most of meiosis's key processes occur during prophase I.
