The second X chromosome does one important function, it gives female chromosomes the ability to correct transcription errors, and for a while some of the radfems were claiming that since Y chromosomes didn't have a second Y to correct errors, males would disappear in time as their genetic code got corrupted.

Now it's been published that Y chromosomes carry duplicates of important sequences so they can correct themselves... women won't be getting rid of us that quickly I'm afriad. Additionally the Y chromosome carries an additional gene for brain development that the X chromosomes doesn't have, although it's function isn't known at this point. [img]smile.gif[/img]

Yes but it has also been published that the Y chromosome contains less and less information. [img]tongue.gif[/img] You wno't be around that much longer. [img]tongue.gif[/img] :D (I'm obviously joking :D ) But the Y chromosome carries several "additional" genes. ;)

[img]smile.gif[/img] Yea the less and less thing was based on the idea that Y chromosomes couldn't repair themselves... I seem to recall one feminist claiming men would be gone within 100 generations or something absurd like that (in their dreams... [img]tongue.gif[/img] ).

What got me about that article was the amount of junk that chromosomes have in them... apparently there are large sections of both the X and Y chromosomes that have dead genes and parts of old genes and just plain garbage code in them.

How this part is easy. It develops the part of the brain that surpresses the desire to ask for directions! [img]graemlins/laugh2.gif[/img]

Yeah some studies have shown that 99% of all our DNA is junk! Left overs from retrovira, evolution etc.
