Is the Y chromosome disappearing? Scientists reveal the new gene that could define future men
In 2002, evolutionary biologist Jenny Graves revealed a provocative calculation in regard to the human Y chromosome, later mentioning that it "is running out of time." Over the past 300 million years, ...
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.
For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...
Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...
In the world of genetics, we are taught that our DNA is a permanent blueprint. However, as men age, a strange phenomenon occurs within their blood: the Y chromosome, also known as the 'Male chromosome ...
