How gametes are formed in the gonads?
In most organisms the gametes are produced by a special double cell division process, a reduction division known as meiosis, in which new cells (gametes) end up with half as many chromosomes as the original cell. The fusion of the egg and sperm at fertilization restores the normal chromosome number.
