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

Unique sex chromosomes occur in species from humans to birds, worms, and flies. An unequal pair of sex chromosomes, each carrying a different complement of genes, requires specific efforts to regulate ...

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 discovered that selfish chromosomes exploit the Overdrive gene to destroy competing sperm during development, increasing their chances of inheritance and shedding light on genetic conflict ...

Researchers at the University of California San Diego (UCSD) have demonstrated an intriguing new variation on the CRISPR gene-editing system, which involves fixing a mutation on one chromosome by ...

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 ...

Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes. So far, little has been known about how the position of a gene on a ...

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 genetic inheritance. The researchers found that ...
