Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males ...

The non-recombining region of the human Y chromosome (NRY), which comprises 95% of the chromosome, does not undergo sexual recombination and is present only in males. An understanding of its ...

Now, they've completed the elusive Y chromosome map. In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart.

Scientists have fully sequenced the Y chromosome for the first time, uncovering information that could have implications for the study of male infertility and other health problems.

The Y chromosome has seen significant changes over the course of human evolution. "In comparison to the X, the Y is tiny. There are only 45 genes on the Y chromosome, ...

Together, more than 100 researchers from across the world have, for the first time, fully sequenced the male sex chromosome—the final mysterious piece of the human genome. “Just a few years ...

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 ...

"It finally provides the first complete view of a Y chromosome's code, revealing more than 50% of the chromosome's length that was previously missing from our genome maps," said University of ...
