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, ...

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: ...

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 ...

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 ...

Now a new preprint research paper posted to the bioRxiv* server dismisses the possibility, raised by that study, that the virus inserts its genetic material into the host cell’s genome. In Germany ...

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 ...

That changed in 2014, when Swedish scientists showed that Y loss in blood cells correlates with how long men live – those who ...

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 ...

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

New research by UCLA Health has identified a sex-chromosome linked gene that drives inflammation in the female brain, ...
