The evolution of South American populations of Trimerotropis pallidipennis (Oedipodinae: Acrididae) revisited: Dispersion routes and origin of chromosomal inversion clines

In the past few years large-scale genome sequencing has demonstrated that inversion rearrangements are more frequent than initially hypothesized. Many examples suggest they may have played an important function in delineating the evolution of biodiversity. In particular, clinal patterns of variation...

description In the past few years large-scale genome sequencing has demonstrated that inversion rearrangements are more frequent than initially hypothesized.
