sperm and egg
The two kinds of sex cells that a gametophyte produces are eggs (female sex cells) and sperm (male sex cells). During sexual reproduction, these sex cells fuse to form a zygote, which develops into a new organism.
The "meiosis" stage in cell reproduction produces two identical sex cells.
I think it's that first of all, sex cells undergo meiosis 1 and 2. None of the others do.
Sex cells have 1/2 the number of chromosomes than body cells. In humans that is 23.

The number of chromosomes doubles in comparison to the sex cells.
