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

X chromosome in cells in the hippocampus, a brain region crucial to learning and memory. And when the researchers gave mature mice of both sexes a type of gene therapy to boost expression of one ...

Horizontal gene transfer (HGT) is the movement of genetic material from one organism to another. In this article, we will ...

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 ...

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

The research reveals that this sex-based difference can be traced to a gene on the Y chromosome. The discovery, published in Science Advances, not only showcases the critical need to understand ...

Childhood-onset striatonigral neurodegeneration robs children of the ability to walk and talk by age five. Researchers at ...

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

The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring ...

requiring athletes who compete in the female category to submit to a cheek swab or dry blood-spot test for the presence of a gene that indicates whether the athlete has a “Y” chromosome ...
