Sex Cells (gametes) are formed during the process of meiosis. That's becuase the process rusults in a cell with one half (haploid) number of chromosomes of the parent cell's chromosomes (diploid).

Mitosis is a process that results in two daughter cells with DNA identical to the parent cell. Meiosis is a process that results in four daughter cells with genetically unique DNA.
