The researchers identified regions with Neandertal ancestry in over 300 individuals. They assessed sharing of segments, inferred gene flow, and looked at variation to identify candidates for positive ...

Understanding the joint effects of gene flow and selection is one of the more important but difficult areas of evolutionary genetics. A method is presented to describe cases of gene flow–selection ...

Despite the traditional view that species do not exchange genes by hybridization, a new study led by Princeton ecologists Peter and Rosemary Grant show that gene flow between closely related species ...

Currently, there are several hypotheses surrounding the disappearance of Neanderthals. While they all have at least some ...

MADISON - In a river valley just southwest of Mexico City stands a small patch of teosinte - a wild, weedy grass thought to be the ancient ancestor of corn. As a gentle breeze blows gene-carrying ...

What are cell and gene therapies? Cell and gene therapies are utilized to treat diseases and, in some cases, cure diseases by targeting the underlying proteins or genes. Overlaps between these ...
