What is the main difference between Mitosis and Meiosis

Well, the main difference between Mitosis and Meiosis is the end product of their respective division.

Now the end product of Mitosis is a daughter cell that has the SAME number of chromosomes as the parent cell. That is, a parent cell starts with "2n" chromosomes (this is known as a diploid), and the daughter cell has the SAME number!

While in Meiosis, the daughter cell has HALF the number of chromosomes as the parent cell. So if the a parent cell starts with "2n" chromosomes (this is known as a diploid), then the daughter cell will have HALF that number; that is, 2n/2 = ''n'' chromosomes (this is known as a haploid).

So, Mitosis = SAME numeber of chromosomes

      Meiosis = HALF the number of Chromosomes
