Cell division in sexual reproduction

Meiosis occurs in sex cells or gametes with only half the original number of chromosomes. 

When sex cells divide the first stage is very much like normal body cell division. The chromosomes are copied so there are four sets of chromosomes. The cell then divides twice in quick succession to form four gametes, each with a single set of chromosomes. 

Why is meiosis important?

Your normal body cells have 46 chromosomes in two matching sets. if sex cells had the same amount then the new cell would have 92 chromosomes, which just wouldn't work. 

Gametes actually have half the number of chromosomes so when they…
