Novel major locus regulates beak evolution of ground tit

Classical quantitative genetics has found that most phenotypes are polygenic traits. Under this polygenic model, natural selection often acts on many loci simultaneously, resulting in the combination of a few loci with major ...

Bread mould avoids infection by mutating its own DNA

Whilst most organisms try to stop their DNA from mutating, scientists from the UK and China have discovered that a common fungus found on bread actively mutates its own DNA as a way of fighting virus-like infections.
