The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: Genes on the Y chromosome are critical for fertility in males. In a new ...

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 ...

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 ...

A new study found that cancer cells selectively chip away gene-rich sections of the Y chromosome, triggering changes that ...

The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: genes on the Y chromosome are critical for fertility in males. In a new ...

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 ...

The Y chromosome keeps grabbing attention in evolutionary science. People often wonder if it is stable, shrinking, or on its way to disappearing. This debate continues because it balances solid ...

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 ...
