The X chromosome is one of the two sex chromosomes in humans, the other being the Y chromosome. It plays a crucial role in determining an individual's sex, with females typically having two X chromosomes (XX) and males having one X and one Y chromosome (XY). The X chromosome contains many genes that are important for various bodily functions and development. In addition to sex determination, the X chromosome is associated with several genetic disorders. Conditions such as hemophilia and color blindness are linked to mutations on the X chromosome. Because males have only one X chromosome, they are more likely to express these disorders if they inherit a mutated gene.
