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

The Y chromosome is an exception, only containing a few dozen genes. DNA is the material carrying all the information about the development and functioning of the individual – the blueprint to ...

It will now be possible to study specific and unique Y chromosome sequence patterns, such as the structure of the two satellites and the location and copy numbers of the genes. Even within the Y ...

Scientists have discovered that the Y chromosome, crucial for male development, is gradually disappearing. This loss, occurring in some men's cells around age 50, is linked to increased risks of ...

The complete Y chromosome sequence could help propel research on this important mystery. 8. Could the Y chromosome ever completely disappear? By comparing the Y chromosome in humans to that of other ...

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 male Y chromosome has disappeared from a species of rat, leading scientists to investigate how humans might also lose ours in the near future.. It's not all bad news for men though, as a paper ...

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 ...
