How many human chromosomes are classified as autosomes?

Humans typically have 46 chromosomes in total, organized into 23 pairs. Of these pairs, 22 are classified as autosomes, which are non-sex chromosomes. The 23rd pair, which consists of the X and Y chromosomes, determines an individual's sex (male or female).

Autosomes contain genes that govern a variety of traits and functions that are not related to sex determination. This arrangement is consistent across all human cells except for gametes, where the chromosome number is halved to 23 total chromosomes.

The classification of chromosomes into autosomes and sex chromosomes is fundamental in understanding genetic traits, inheritance patterns, and certain genetic disorders. Thus, recognizing that there are 22 pairs of autosomes in humans is crucial for topics related to genetics and evolution.
