Meiosis is a process in which a single cell divides two times to produce four daughter cells, each with half as much genetic material as the mother cell.
The number of chromosomes in these four daughter cells is half that of the parent cell.
Meiosis is a process that happens in all animals and plants.
Although the ultimate outcome, gametes with half the number of chromosomes as the parent cell, is the same, the detailed procedure is different.
