X chromosome, source of gender and many diseases, is laid bare

Quotes from this article:
"The Y chromosome has steadily eroded to a little stump over the millennia, a process that holds out the intriguing theory that men may eventually be eliminated by evolutionary pressure.
The Y now has less than 100 genes... X chromosome... a whopping tally of 1,098 genes on it, about four percent of the total on the entire genome.
Seeking to understand this remarkable difference between X and Y, the team believes the two chromosomes evolved from humble beginnings as an "ordinary" pair of identical chromosomes in a sex-less organism.
Changes to a gene on one of the pair triggered the molecular cascade that led to male development, and set in train the degeneration of Y chromosome to its present rump-like state."

I wonder if a woman wrote the article.. haha

Anyway, here's a version of the article by the institute itself. And I still haven't found out what diseases are coded by the X chromosome.. Maybe the results are patented or sth.
