An '''autosome''' is a non-sex [[chromosome]]. It is an ordinarily paired<ref>In the case of higher [[ploidy]] levels than the usual diploid, there will be the same number of an autosome as the ploidy level itself. For example, in a pentaploid, there will be five copies of each autosome.</ref> type of chromosome that is the same in both [[sex]]es of a [[species (biology)|species]]. For example, in [[human]]s, there are 22 pairs of autosomes. The X and Y chromosomes are not autosomal. Non-autosomal chromosomes are usually referred to as [[sex chromosome]]s, allosomes or heterosomes.
