The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

“We completed the wiring diagram for all these genetic switches that get activated via the Y chromosome,” Michael Schatz, a professor at Johns Hopkins, said in a news release, “many of which ...

Despite its macho connotations, the Y chromosome is among the tiniest of the 46 chromosomes in the human genome. It makes up only 2 percent of a human cell’s total DNA.

While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

The human Y did once contain as many genes as the X chromosome, but has lost them in the past 166 million years. As a result, most of the Y today is made up of repetitive "junk DNA." ...

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact trigger for such degeneration is unknown, environmental factors can play a ...

DNA of the male-determining Y chromosome has been completely sequenced end-to-end, and it’s just as weird as we expected. Will we finally be able to understand how it works?

All the chromosomes do this: chromosome 1 from mom swaps arms with chromosome 1 from dad, and so on. The Y, however, does not have a swapping companion.

The Y chromosome in primates — including humans — is evolving much more rapidly than the X chromosome, new research on six primate species suggests. For instance, humans and chimpanzees share ...

It's common for men to lose the Y chromosome in their cells as they age. But a new study finds a strong link to bladder cancer, and a potential therapy for it.
