Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male ...

By late life, a surprising share of men have blood cells that no longer carry the Y chromosome at all, according to large genetic studies in cohorts such as the UK Biobank. That quiet genetic drift ...

Recent research indicates that the loss of the Y chromosome in older men is linked to severe health conditions such as ...

Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter lifespans.

The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

Men tend to lose the Y chromosome from some of their cells as they age — a process once thought to be harmless because the Y carries relatively few genes beyond those involved in male determination.

Scientists have decoded the Y chromosome in full for the first time. In a new article published Aug. 23 in Nature, scientists with the Telomere-to-Telomere, or T2T, consortium—a group of researchers ...

X chromosome reactivation contributes to reducing the signs of disease in the female brain. Female cells have two X ...
