Verified step by step guidance1
Understand that human somatic (body) cells are diploid, meaning they contain two sets of chromosomes, one from each parent, totaling 46 chromosomes.
Recognize that gametes (sex cells) are produced through meiosis, a special type of cell division that reduces the chromosome number by half to maintain species chromosome number after fertilization.
Recall that meiosis results in haploid cells, which contain only one set of chromosomes.
Since humans have 46 chromosomes in diploid cells, the haploid number in gametes is half of that, which is calculated as \(\frac{46}{2}\).
Therefore, the number of chromosomes in a mature human gamete after meiosis is 23.
