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

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 ...

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

Researchers 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 produce enough ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Three specific genes on chromosome 21 drive widespread brain changes in Down syndrome, uncovering a new framework for ...

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery-how "selfish chromosomes" cheat the rules of ...

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 ...

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 ...
