When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...

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

Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome separation during cell division. By studying related yeast species, ...

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.

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

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

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

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 ...

Autism spectrum disorder (ASD) is a neurological and developmental condition that can be diagnosed at any age, although the symptoms tend to appear in the first two years of a patient's life. ASD can ...

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

Researchers at the Johns Hopkins Kimmel Cancer Center and its Ludwig Center uncovered new evidence that extra copies of a ...
