About the X chromosome

The X chromosome is one of the 2 chromosomes which determines sex. The X chromosome is also much more complex and carries far more genes than the Y; in fact they carry 2,000 : 50 respectively. There are certain abnormalities where people can have extra X chromosomes or other abnormalities in this chromosome. Because both males and females have X chromosome any chromosome abnormalities may manifest themselves in different ways. Some examples of X chromosome autosomal abnormalities include Klinefelter syndrome and Trisonomy X.
