New techniques to detect Y chromosome genes show frequent loss of the Y in tissues of older men. The increase with age is ...

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 ...

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 ...

By late middle age, as many as four in ten men have quietly lost the Y chromosome in some blood cells. Scientists are now ...

Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...

As men age, many quietly lose the Y chromosome in some cells, and scientists now link this hidden change to heart disease, cancer and even shorter lifespans.

You might think that your genes are relatively stable, and that your chromosomes will remain roughly the same over the course ...

Newly generated, complete genomes for the sex chromosomes of six primate species — produced by an international collaboration led by researchers at Penn State and the National Human Genome Research ...
