X chromosome
The female sex chromosome, which following sexual reproduction is inherited from each parent in females, and inherited from the mother in males. This inheritence pattern impacts upon the pattern of genetic disease.
(More? X Chromosome)
Xist
The name for a non-translated RNA (18 Kb) that is associated with the inactivated X chromosome in female cells to correct for the double gene dosage, 2 copies of teh X chromosome.

X inactivation
Process that occurs in all cells within females, each cell has 2 copies of the X chromosome (one from father and one from mother) one of copy of which is randomly inactivated throughout the entire body in order to maintain gene dosage.
(More? Molecular Development - X Inactivation | X Chromosome | Week 1 Notes)
X linked
Term used to refer to genes, and genetic diseases, located on the X chromosome. Therefore more likely to be expressed in males, where there is only a single maternal X chromosome.
