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 ...

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 ...

India, March 17 -- Selfish chromosomes bias genetic inheritance by manipulating the overdrive (Ovd) gene, a natural sperm quality control checkpoint.

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery—how "selfish chromosomes" cheat the rules of genetic inheritance. The researchers found that ...

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

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

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

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 ...

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 ...

The lab of developmental biologist Dr. Eric Lai has been studying evolutionary battles of the sexes in fruit flies. This colorful snapshot, courtesy of the Lai Lab, depicts sperm maturation in fruit ...

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 ...
