Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the ...

When X-linked genes evade silencing on the “inactive” chromosome in XX cells, some protect women from diseases such as cancer, but others seem to promote conditions such as autoimmunity. Amber Dance ...

Scientists discover that women's second X chromosome awakens later in life, expressing genes that protect the brain from ...

Females carry two X chromosomes. One of them is ensconced in a corner in the cell called the Barr body, where it can't express many genes, and scientists thought it didn't do much of anything. But the ...

A new study out of the University of California San Francisco indicates that women’s brains might be better suited for aging, ...

Females, on average, live nearly five years longer than males. They also tend to experience age-related cognitive decline at ...

one would have expected zero to two of the genes to be X-linked. Our findings indicate that the X chromosome has a predominant role in pre-meiotic stages of mammalian spermatogenesis. We ...

The overlooked influence of this genetic library could be a key reason why females live longer than males and exhibit slower ...

While you've likely heard of common cat coat types such as tabby and calico, you may not have heard of the torbie. Here's ...

Researchers have shed new light on how a type of heart valve disease—aortic valve stenosis—progresses differently in males and females. The research paves the way for treatments that can be tailored ...

Scientists at the University of California, San Francisco (UCSF) may have uncovered a key reason why women tend to outlive men and maintain better cognitive function as they age. Their research ...

Researchers found that a gene on the Y chromosome influences how aortic valve stenosis progresses differently in males and ...
