Identify the diploid chromosome number (2n) given in the problem, which is 46 chromosomes for the somatic cells of the organism.
Recall that meiosis consists of two divisions: meiosis I and meiosis II. At the end of meiosis I, homologous chromosomes are separated, but sister chromatids remain together.
Understand that after meiosis I, each daughter cell is haploid (n), meaning it contains half the number of chromosomes compared to the diploid parent cell.
Calculate the haploid number (n) by dividing the diploid number (2n) by 2: \(n = \frac{2n}{2}\).
Conclude that each daughter cell at the end of meiosis I contains \(n\) chromosomes, which is half of 46, so 23 chromosomes.
