A chromosome that is not a sex chromosome. In other words, any one of the chromosomes save the sex chromosomes. People normally have 22 pairs of autosomes in every cell (together with two sex chromosomes — an X and a Y in the male and two Xs in the female — for a total of 46 chromosomes). The term "autosome" was coined by Montgomery in 1906.
