Understand that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent, totaling 46 chromosomes.
Recognize that meiosis is the process by which diploid cells produce haploid gametes (sperm or egg cells), reducing the chromosome number by half.
Recall that after meiosis is complete, each gamete contains only one set of chromosomes, which is half the diploid number.
Calculate the haploid number by dividing the diploid number (46) by 2, using the formula: \(\frac{46}{2}\).
Conclude that a mature human sperm cell contains 23 chromosomes, which is the haploid number.
