An easy route to the massive karyotyping of complex chromosomal arrangements in Drosophila.

ABSTRACT: Inversion polymorphism is widespread in the Drosophila genus as well as in other dipteran genera. The presence of polytene chromosomes in some insect organs and, thus, the possibility to observe the different arrangements generated by inversions through a microscope enhanced the cytological study of this structural polymorphism. In several Drosophila species, these studies provided evidence for the adaptive character of this polymorphism, which together with the standing interest to uncover targets of natural selection has led to a renewed interest for inversion polymorphism. Our recent molecular characterization of the breakpoint regions of five inversions of the E chromosome of D. subobscura has allowed us to design a PCR-based strategy to molecularly identify the different chromosomal a
