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 ...

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.

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 ...

Why the Y Chromosome Back to Build a Family Tree All men and only men have a Y chromosome. This biological fact allows us to trace back in time a direct, largely unchanged genetic line of ...

There are only 45 genes on the Y chromosome, and it is just one of these that makes you male," Jenny Graves, a geneticist and ...

Researchers mapped Y chromosome loss across thousands of individual cells from human cancers, with disturbing results.

The Y chromosome is only about one-third the size of the X and contains far fewer genes.Now, scientists have found that this smaller chromosome can actually degrade over time.

The Y chromosome, along with the X chromosome, is often discussed for its role in sexual development. While these chromosomes play a central role, the factors involved in human sexual development are ...

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

Page agreed. "The Y chromosome has many more tricks up its sleeve than it was given credit for," he said. There are a couple of reasons Page and Hughes cite for Y being such an evolutionary ...
