Understand that the diploid number (2n) represents the total number of chromosomes in a somatic (body) cell of the organism. Here, the diploid number is given as 12.
Recall that gametes (sperm and egg cells) are haploid cells, meaning they contain half the number of chromosomes compared to diploid cells.
Recognize that meiosis is the process that reduces the chromosome number by half to produce haploid gametes from diploid cells.
Calculate the haploid number (n) by dividing the diploid number (2n) by 2 using the formula: \(n = \frac{2n}{2}\).
Apply the formula to the given diploid number: \(n = \frac{12}{2}\), which gives the number of chromosomes in each gamete.
