meiosis and mitosis

This week we started to learn about meiosis. Its a 11 step process and makes four (tetra) animal cells. The phases/ steps are:
  1. diploid cell (2N)
  2. prophase I
  3. metaphase I
  4. anaphase I
  5. telophase I
  6. prophase II
  7. metaphase II
  8. anaphase II
  9. telophase II
  10. gamete (1N)
  11. material paternal
Also in meiosis four cells are being made instead of just one, like in mitosis. Also both mitosis and meiosis have overall the same phases, except for meiosis has it has double the phases like prophase I and prophase II. Meiosis also creates animal cells as appose to mitosis which makes any type of cell. Lastly, Meiosis has two adde phases called diploid cell (2N) which occurs at the begining of the cycle and gamete which takes place at the end of meiosis.
