A follow-up over 83 generations has been carried out, by the Southern blotting technique, of a Drosophila stock which is unstable in the location of Bari 1 elements. The persistent intrastock polymorphism detected is largely amenable to insertion/excision equilibria at 36 genomic sites that form a gradient in occupancy. In a closely related stock, Bari 1(More)
The white-spotted-1 (Wsp1) mutant of Drosophila melanogaster is characterized by the presence of an 8.7 kb retrotransposon (B104) inserted in the regulatory region of the white locus. The frequency of reversion in both somatic tissue and the germline after exposure to three different alkylating agents has been analysed. To determine if germinal revertants(More)
It has been suggested that transposable elements can be associated with different types of genotoxic effects. For this reason it seems appropriate to outline suitable systems to detect changes in the phenotypic expression of the loci containing transposable elements, as well as those agents that induce such changes. The sex-linked white locus offers a(More)
