Giraffes have 30 chromosomes in their somatic cells, which are diploid (2n). During meiosis, the number of chromosomes is halved to produce gametes (sperm or eggs), which are haploid (n).
To find the number of chromosomes in each daughter cell after meiosis, you divide the diploid number by 2:
\[ n = \frac{30}{2} = 15 \]
Therefore, each daughter cell will have 15 chromosomes after the final step of meiosis.
