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.

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. But because of its ...

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 ...

"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 ...

The Y chromosome can disappear over time in human males, which may introduce a number of health problems. While the exact ...

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.

By comparing the X and Y chromosomes to each other and among species, including to the previously generated human T2T sequences of the X and the Y, we learned many new things about their evolution.” ...

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 professor at the La Trobe Institute for Molecular Science, said to BBC ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don ...

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.
