Chromosomal inversions effect body size and shape in different breeding resources in Drosophila buzzatii

The cactophilic Drosophila buzzatii provides an excellent model for the study of reaction norms across discrete environments because it breeds on rotting tissues (rots) of very different cactus species. Here we test the possible effects of second chromosome inversions on body size and shape (wing lo...
