How many chromosome pairs are present in a normal human?

Explanation:
Humans in normal body cells are diploid, with 46 chromosomes arranged as 23 homologous pairs. Most of these pairs are autosomes (22 pairs), and the remaining pair is the sex chromosomes (XX in females, XY in males). So the total number of chromosome pairs is 23. When gametes form, they carry 23 unpaired chromosomes, and fertilization combines them to make 46 again in the embryo.
