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. Figure 1: A representation of a condensed eukaryotic chromosome, as seen during cell division. ...

Non-autosomal chromosomes are usually referred to as sex chromosomes, allosomes or heterosomes. An autosomal dominant gene is one on an autosome that is always expressed, even if a single copy exists. The chance is 1 in 2 (50%) for passing this autosomal dominant gene to a particular offspring. There are 23 pairs of chromosomes in humans (44 autosomes, 2 sex chromosomes). A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. ...
