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 ...

In the ongoing effort to determine just how much of who we are is preordained by our genetic code, heritability, a statistical measurement of how much variation in a trait can be attributed to genetic ...

What determines how long we live—and to what extent is our lifespan shaped by our genes? Surprisingly, for decades, ...

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 ...

The research, published in Science, argues that the true genetic contribution to the variation in human lifespan has 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 ...

Many factors influence how long you live, such as diet, exercise, smoking, drinking, environment and other variables. It also ...

By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than ...

A sweeping genomic analysis reveals how psychiatric disorders cluster into five biological families, exposing shared pathways and pinpointing where their genetic roots diverge. Study: Mapping the ...
