New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.

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, ...

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago. A new ...

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago.

Thin stretches of the human X chromosome look oddly empty when you scan for Neanderthal DNA. Geneticists even have a name for the gaps: “Neanderthal deserts.

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

Learn how sex-biased interbreeding between Neanderthals and modern humans explains why Neanderthal DNA is largely missing ...

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 ...

Highly challenging to sequence and long overlooked, the human Y chromosome’s contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

An international research team has generated the first truly complete sequence of a human Y chromosome, the final human chromosome to be fully sequenced. The new sequence, which fills in gaps across ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
