(PhysOrg.com) -- Gene duplications are arguably the driving force of organismal evolution – and if they survive, such duplicate genes will diverge in both regulatory and coding genomic regions. Coding divergences, in ...
A new University of Florida study shows a hybrid plant species may experience rapid genome evolution in predictable patterns, meaning evolution repeats itself in populations of independent origin.
