<span>Autosomes are
non-sex chromosomes, meaning they are non-sex determining chromosomes inside
cells. Humans naturally have 46 chromosomes in each body cells; 44 of these are
actually autosomes that a person inherits from his/her parents. All persons get
22 autosomes from the mother and the other 22 autosomes will be coming from the
father. These autosomes always come in pairs and since everyone has 44 of these
autosomes in their cells, it should be noted that there are only 22 types that
are obviously numbered from 1 to 22. </span>
