For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than 50 ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

Biological science has made such astonishing leaps in the last few decades, such as precise gene editing, that scientists are now tackling the next logical — yet inherently controversial — step: ...

Micronuclei and Y Chromosome Loss: The formation of micronuclei, small cellular structures containing chromosomes or fragments, plays a critical role in the disintegration of the Y chromosome, linking ...

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 ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

A condition known as Robertsonian translocation occurs when the long arms of two chromosomes join together. The characterization of the fully sequenced and assembled fused chromosomes reveals a common ...

Jenny Graves is a Friend of The Conversation. 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 ...

Non-Africans carry around 2% Neanderthal DNA in their genomes — yet there's one chromosome where DNA from our ancient cousins is nowhere to be found. When you purchase through links on our site, we ...
