By the age of 70, about 40% of men have lost the Y chromosome in at least some of their white blood cells. This condition, ...

Scientists at the USC Leonard Davis School of Gerontology have discovered a key connection between high levels of iron in the ...

Editor—Tetrasomy 21 without mosaicism has previously been described in four liveborn children, two of whom had physical features consistent with Down syndrome. We describe a male infant with partial ...

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such ...

See a Vibrant, Colorful Mosaic Discovered at an Ancient Roman Settlement in France Perched on a hill overlooking the town of Alès, the site, which was salvaged before construction on modern ...

Hundreds of thousands of chromosome studies are performed each year on peripheral lymphocytes, skin fibroblasts, amniotic fluid cells and chorionic villus tissue, and rates of mosaicism for ...

Mosaic Loss of Y (LOY): A Prevalent Phenomenon Long before the Y chromosome potentially vanishes from the human species, many men are already experiencing its loss within certain cells. Commencing ...

Scientists are expressing concerns about male reproductive health due to the Y chromosome's genetic material loss, potentially disappearing in 11 million years. A study revealed a sharp decline in ...

Researchers mapped Y chromosome loss across thousands of individual cells from human cancers, with disturbing results.

Flip open a high-school biology textbook, and the rule seems tidy: two X chromosomes mean girl, and an X paired with a Y means boy. That much smaller Y chromosome carries the SRY gene, which is the ...
