SAN FRANCISCO — A genetic coin toss that happens before birth might influence how women’s brains age decades later. A study ...

AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

Researchers from the University of California, San Francisco (UCSF) say they have now found that when the brain cells of female mice express only a maternal X chromosome, the animals’ memory and ...

In a recent review article published in the journal Nature Reviews Immunology, researchers synthesize the current knowledge on how having two X chromosomes affects the composition and function of the ...

About two-thirds of people with Alzheimer’s disease are women, yet due to the challenges in studying X chromosomes, a genetic foundation for this has been difficult to uncover. Now, two large ...

Researchers have found that a carefully orchestrated act of X-chromosome 'yoyo' predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating ...
