Meiosis

Key Questions

• What is meiosis?

  Answer:

  Meiosis is a type of cell division in which reduces the number of chromosomes by half.

  Explanation:

  Meiosis (not to be confused with mitosis) occurs in every sexually reproducing eukaryote and is required to produce egg and sperm cells. The result of meiosis is four daughter cells.
