An autosome is a chromosome that is not a sex chromosome ' that is to say there are an equal number of copies of the chromosome in males and females. For example, in humans, there are twenty-two pairs of autosomes, and, in addition, there are the X and Y sex chromosomes.
|There are two copies of each autosome (chromosomes 1-22) in both females and males. The sex chromosomes are different: there are two copies of the X chromosome in females, but males have a single X chromosome and a Y chromosome.
