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 the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...
Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one X and one Y chromosome. According to Medline Plus, in every cell, humans ...
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males ...
For years, we’ve been taught that men have one X and one Y chromosome, with the Y carrying the vital gene that initiates male development. But now, scientists are sounding the alarm: the Y chromosome ...
Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...
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 ...

Men lose their Y chromosome as they age. Scientists thought it didn't matter - but now we're learning more
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 ...
Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...
Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...
