Sex talk revelations of the lonely Y chromosome
Date:9/10/2009

ined much the same, but the Y set out on a path of degeneration that saw it lose many of its genes and shrink to about one third the size of the X. Some scientists have predicted that it will eventually vanish altogether.

"These new findings from the Department of Genetics of the University of Leicester now challenge this interpretation of the Y chromosome's fate."

The Leicester researchers discovered that the conversation between the X and Y chromosome goes both ways, and it's also clear that mutations arising on a decaying Y chromosome can be passed to the X the Y chromosome's revenge, perhaps! Future work will assess how widespread X-Y exchanges have been during evolution, and what the likely functional effects might be.
