Solution

Chromosome number in humans is 46.

Explanation:

The somatic (body) cells of normal human beings contain a diploid set of 46 chromosomes, arranged perfectly into 23 distinct pairs. Out of these, 22 pairs are matching autosomes that control general body traits, while the remaining 1 pair consists of sex chromosomes (XX in females or XY in males). Gametes like sperm and egg cells are haploid and contain exactly half this number, which is 23 chromosomes.
