Just like life. The female gene goes to it's partner when something is broken, the male gene fixes it on it's own.
i would just like to point out that this research in fact illustrates that men are not going to become extinct and we are not genetically inferior.
ABC News wrote:Broken genes tend to erode away over eons. But because most chromosomes are inherited in pairs, with one coming from Mom and the other from Dad, they can swap corresponding pieces of themselves, enabling the species as a whole get rid of damaged genes.
But the Y chromosome comes by itself. It cannot trade appreciable amounts of DNA with its partner, the X chromosome, so it cannot get rid of damaged genes that way. That has led some scientists to regard it as a "rotting chromosome" that might disappear millions of years from now.
The new work found that the Y chromosome follows a do-it-yourself strategy: It carries backup copies of important genes, and it uses one copy to fix flaws in the other.
