The human Y chromosome - the DNA chunk that makes a man a man - has lost so many genes over evolutionary time that some scientists have suspected it might disappear in 10 million years. But a new study says it'll stick around.

The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates. While the human Y has maintained its count of 27 genes and gene families, some of these same genes on the chimp Y have mutated and gradually become inactive. The authors speculate that one likely reason for such disparity is due to chimpanzee mating habits.

Breakages in chromosomes in mammalian evolution have occurred at preferred rather than random sites as long thought, and many of the sites are involved in human cancers, an international team of 25 scientists has discovered.

Women get more work out of hundreds of genes on the X chromosome than men do, and that could help explain biological differences between the sexes, a new study says. The results imply that women make higher doses of certain proteins than men do, which could play out in gender differences in both normal life and disease, researchers said.
