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 ...

Historic population bottlenecks left cheetahs genetically similar, increasing disease risk and threatening long-term survival ...

Are human beings as unique as snowflakes? Not quite, but new research shows humans may have a lot more individuality than originally thought -- in fact, the genetic codes of people can vary by as much ...

Clinicians' ability to diagnose and treat chronic diseases is limited by scientific uncertainty around factors contributing to disease risk. A study published September 2 nd in the open-access journal ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

Aortic stenosis is a narrowing of the aortic valve which connects the heart to the rest of the body. It affects millions of people and can be fatal if left untreated. At present, there are no ...

This large-scale genomic analysis of 14 psychiatric disorders shows that most heritable risk is shared across five broad genetic factors, with only limited disorder-specific variation. The study maps ...

A study suggests psychiatric disorders can share the same genetic signatures and that they may stem from shared biological ...
