A series of subpopulations earlier obtained were studied for hybridization of mobile genetic elements (MGE). The subpopulations examined were two "selected" (ris- and ris+), two "temperature" (ri(c113) and ri(c149)) and the control (ric). The method of in situ hybridization with polytene chromosomes of larval salivary glands was used to determine the patterns of MGE localization for all subpopulations. The patterns obtained appeared to be quite different from that of mdg-2. The trees of similarity for subpopulations according to the patterns of every MGE localization were built by conventional clustering methods. These trees were topologically similar to each other and to mdg-2. Distinction spectra of patterns of four daughter subpopulations, in comparison with the control one, were shown for each of these MGE to be independent and individual. However, there are some common regularities among copia-like MGE-mdg-1, copia, mdg-2 and, probably, mdg-3, namely: non-random property of the majority of changes, the similarity of patterns for subpopulations with similar phenotypes etc. So, Drosophila genome can be conceived as a complex system of patterns of different MGE localization, capable of common or independent mass transpositions after external stress action.
