Researchers at Linköping University in Sweden made an unexpected discovery while investigating genetically unique women.

UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's ...

Study reveals the impact of X chromosome on brain aging in women. Learn how maternal and paternal X chromosome can influence cognitive abilities.

A high-quality genome assembly of Silene latifolia was generated by researchers at CNRS/Université Claude Bernard Lyon 1 and ...

Patients with Klinefelter and triple X syndromes show an increased prevalence of SLE and Sjögren disease, likely due to the synergistic interaction of the extra X chromosomes.

Some fish have a gene that determines sex, but not a whole chromosome. Even in humans, the X/Y sex chromosome system isn't as clear-cut as it might look on paper; gene mutations or inheriting ...

Dating back 480 million years, octopuses have one of the oldest known sex chromosomes, according to a new study published in Current Biology. The study unveils that octopuses determine their sex ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is linked to faster brain aging. The X chromosome passed from mom to ...

Science has revealed some of the secrets of the X chromosome, but many remain. In humans, female cells contain two X chromosomes (XX) and male cells contain one (XY). In each female cell ...
