Reference genome choice compromises population genetic analyses

Using a species-specific reference genome significantly improves the accuracy of population genetic analyses, as exemplified by mapping gray fox sequence data to genomes of several canid species. Mapp...

Finally ready to see the world! Theories of balancing selection - past, present and future: www.biorxiv.org/content/10.1... A true collaborative effort that brought together theoreticians and empiricists, models, data, and fresh perspectives on how balancing selection can shape genetic variation.

A century of theories of balancing selection

Traits that affect organismal fitness are often very genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature (...
