title: [Species architecture of generative tissue chromosomes and problems of phylogenetic relationships in the melanogaster subgroup of the Drosophila genus (Sophophora)].
abstract: An analysis was carried out of the peculiarities of interlocation of primary ovarian trophocyte polytene chromosomes of Drosophila sechellia in comparison with seven earlier-described species of the melanogaster subgroup. Based on the data from this analysis and earlier-known results of reconstruction of the reconstruction of the subgroup phylogeny, the following trend in the evolution of the architectonics of trophocyte chromosomes is suggested: from a local tight chromocenter (D. orena), to a diffuse chromocenter (D. erecta, D. simulans, D. sechellia), to its complete disappearance (D. yacuba, D. mauritiana), and to tight binding of chromosomes to the nuclear membrane (D. teissieri, D. melanogaster).
