Abstract excerpt
The Rhagoletis pomonella species group has for decades been a focal point for debate over the possibility of sympatric speciation via host shift. Here I present the first extensive analysis of genetic (allozyme) divergence in the pomonella group, including all known taxa/populations except the allopatric Mexican population of R. pomonella. The phylogeny is estimated for all four described species (pomonella,...
