Summary
In the P-M system of hybrid dysgenesis inDrosophila melanogaster, the cytotype corresponds to an extrachromosomal state which controls the mobility of the P transposable elements. Previous experiments have shown that thermic treatments during development and ageing may dramatically influence the cytotype transformation process in certain types of hybrid females. We show here that these temperature-induced modifications can be detected in subsequent generations. The consequences for the cytotypic characterisation of strains are discussed.
