Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

Rapidly testing hundreds of thousands of DNA sequences, scientists identified specific genetic variations contributing to blood pressure, cholesterol, and blood sugar.

Many human traits are influenced by multiple genes. Human genes can also carry slight variations in their gene sequences, which can have a wide range of effects. In some complex traits, those small ...

David Rand, a professor of natural history at Brown University, explains how studying mitochondria — the cell's energy producers — offers a useful way to understand complex gene-by-gene or ...

The Collaborative Cross (CC) mouse resource has emerged as an indispensable platform for elucidating the genetic basis of complex traits. By combining high levels of genetic diversity from eight ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

Scientists have developed a new method of genetic analysis, which extracts more precise data than previously used methods when looking at DNA, and will improve our understanding of the genetic basis ...

A growing body of genetic evidence suggests that Neanderthals and Denisovans carried many of the same regulatory gene networks linked to language and vocal anatomy in modern humans, challenging the ...

Genes may play a bigger role in living a longer life, while lifestyle and luck still shape the outcome, according to a new ...

Ancient microbes tied to our earliest ancestors could use oxygen, reshaping ideas about how complex life began on Earth.
