An autosome is a non-sex chromosome. It is an ordinarily paired[1] type of chromosome that is the same in both sexes of a species. For example, in humans, there are 22 pairs of autosomes.
The X and Y chromosomes are not autosomal. Non-autosomal chromosomes are usually referred to as sex chromosomes, allosomes or heterosomes.
