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]
