Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

Researchers at a lab in Kansas City believe they have made a breakthrough discovery in understanding infertility.

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

Humans and Neanderthals cozied up from time to time when they lived in the same areas tens of thousands of years ago.

Researchers found three master genes that alter brain development in Down syndrome, offering new clues about learning and memory differences.

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

Three specific genes on chromosome 21 drive widespread brain changes in Down syndrome, uncovering a new framework for ...

New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.

Analysing the births of a Utah family over seven generations has revealed that their disproportionate number of boys could be caused by a selfish Y chromosome ...
