In X-inactivation, females express only one X chromosome in each cell, meaning that genes on the X chromosome are expressed singly instead of in a pair.

This chromosome is gene poor and a specific area called sex determining region on Y (SRY) is responsible for the initiation of the male sex determination. The X-chromosome is rich in genes while the Y-chromosome is a gene desert. The presence of an X-chromosome is absolutely necessary to produce a viable life form and the default gender of mammals is traditionally female.

It covers pseudo-autosomal regions that facilitate recombination between X and Y chromosomes, and illustrates how sex-linked genes diverge from Mendelian inheritance due to sex chromosome influence and dosage compensation. Examples from Drosophila and birds are provided.
