Meiosis is the cell division which leads to the production of sex cells or gametes. It takes place in the reproductive organs (testis and ovary in animals; anthers and ovary in plants).
The number of chromosomes in each daughter cell is half of that in the parent cell. Hence, this division is also called the reductional division.
In contrast to Mitosis where two daughter cells are formed, Meiosis leads to the generation of four daughter cells.
