Verified step by step guidance1
Understand that human somatic cells are diploid, meaning they contain two sets of chromosomes, one from each parent, totaling 46 chromosomes.
Recall that meiosis is the process by which germ cells (sperm and egg) are produced, and it reduces the chromosome number by half to maintain species chromosome number after fertilization.
Recognize that meiosis results in haploid cells, which contain only one set of chromosomes, so the chromosome number in mature sperm cells is half of 46.
Calculate the haploid chromosome number by dividing the diploid number by 2: \(\frac{46}{2}\).
Conclude that a mature sperm cell contains 23 chromosomes, which is the haploid number in humans.
