What is Meiosis?

Saturday July 19, 2008

Meiosis is a two-part cell division process in organisms that sexually reproduce.

Meiosis produces gametes with one half the number of chromosomes as the parent cell.

There are two stages of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced.

Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.
