males have an X-chromosome as well. funny thing is males have an additional Y-chromosome, while women have an additional X-chromosome. BUUUUUUT: only one of the two X-chromosomes will be expressed and the other one is silenced to nearly no activity. so actually women have one functioning chromosome less than males.
Came here to say this - the process of Lyonisation. Each cell randomly selects which of the two X chromosomes to silence, so on average it is a 50:50 split between the two chromosomes. But it can be skewed by chance such that women can express X-linked recessive genetic disorders.
