The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

Animal breeding has traditionally focused on improving mean trait performance; however, contemporary research increasingly highlights the significance of genetic variation not only in trait means but ...

Researchers have demonstrated a specific type of genetic variation in obsessive-compulsive disorder (OCD) for the first time using advanced DNA sequencing technology. The findings support previous ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

A new study by UCLA Health published in Cell presents a major advancement in the future of personalized medicine by pinpointing new connections between people's genes, disease risk and medicine ...

Knowing how human DNA changes over generations is essential to estimating genetic disease risks and understanding how we evolved. But some of the most changeable regions of our DNA have been ...

WASHINGTON — Two-thirds of animal and plant populations are declining in genetic diversity, which makes it harder to adapt to environmental changes, according to research published Wednesday. Long ...

Earth's biodiversity is in crisis. An imminent "sixth mass extinction" threatens beloved and important wildlife. It also threatens to reduce the amount of genetic diversity—or variation—within species ...

Even a single gene, reshuffled or regulated in new ways, can fuel repeated bursts of evolutionary innovation, according to a recent study of wheatear birds. A study was recently published in the ...
