Somatic cell chromosomes occur in pairs. So, if you mean 12 chromosomes, that will be 6 pairs of chromosomes. The corresponding gamete (sex cell) will therefore contain 6 chromosomes

Explanation:

One chromosome from each pair-ish ends up in one gamete. I say 'ish', as there is a certain amount of exchange of genetic material between chromosomes during meiosis (cross-over).
