Understand the definitions: The diploid number (2n) is the total number of chromosomes in a somatic cell, which includes two sets—one from each parent. The haploid number (n) is the number of chromosomes in a gamete (sex cell), which contains only one set.
Identify the given information: The organism's diploid number is 12, so $2n = 12$.
Recall the relationship between diploid and haploid numbers: The haploid number is half the diploid number, so $n = \frac{2n}{2}$.
Substitute the given diploid number into the formula: $n = \frac{12}{2}$.
Conclude that the haploid number is the result of this division, representing the number of chromosomes in the gametes.
