What is the number of pairs of autosomes in humans?

In humans, there are a total of 23 pairs of chromosomes, which include 22 pairs of autosomes and 1 pair of sex chromosomes (XX in females and XY in males). Autosomes are the chromosomes that are not directly involved in determining the sex of an individual. Therefore, the correct answer is that humans have 22 pairs of autosomes. Each pair consists of homologous chromosomes, where one is inherited from the mother and one from the father, totaling 44 autosomes in each human cell (22 pairs). This fundamental understanding of human genetics forms the basis for exploring inheritance patterns, genetic disorders, and other phenomena in anatomy and physiology.
