Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

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 ...

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 ...

Individuals that share the same deletion of a portion of chromosome 16 are at risk of developing neurodevelopmental disorders, but some experience severe intellectual disability or developmental delay ...

In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs) affect genetic activity. The research helps ...

Birds have developed a unique evolutionary solution to ensure the survival of males—a powerful microRNA. This tiny gene allows male embryos to survive despite a genetic imbalance between the sexes by ...

Here’s a quick reality check: ice cream sales go up in summer, and so do drownings. But no one thinks Ben & Jerry's is a silent killer. It’s correlation, not causation. Yet this same logical ...

Translocations are chromosomal “cut and paste” errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but ...
