Genomic analysis of three Neanderthals shows unusually high modern human DNA on the X chromosome offering clues about ...

Females carry two X chromosomes, after inheriting one from each parent. In order to stop serious problems from arising, cells of the body silence one of those X chromosomes in a process known as X ...

The reason female brains have less cognitive aging may be due to the reawakening of the dormant X chromosome late in life, which turns on genes that help sustain healthy brain cell connections. This ...

Researchers found that interbreeding between Neanderthals and early modern humans favoured male Neanderthals mating with female modern humans.

A new study published in Nature Genetics by the Lymphoid Development Group at the MRC Laboratory of Medical Sciences has reveals that the contribution of cells expressing maternal or paternal X ...

In a surprise, work in mice has found that the dormant X chromosome in females can reawaken late in life and turn on genes that keep the brain healthy. UCSF researchers may have discovered how the ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.
