Science Blog - Genes expose secrets of sex on the side: "The researchers started looking at bits of the Y chromosome known as the Alu family of retrotransposons.
''We found lots of Y-chromosome variations that people didn't know exist,'' Wilder said.
The new technique revealed that Y-chromosome DNA and mitochondrial DNA differ to the same degree among populations.
Hammer said, ''That alone wouldn't say the Y chromosome is migrating more, but if just half as many males are getting their genes into the next generation on average as are females, then it implies more males are migrating to do that.''"
