[Systemic reorganization of the architectonics of polytene chromosomes in the onto- and phylogenesis of malarial mosquitoes. II. Species specificity in the pattern of chromosome relations with the nuclear envelope of nutrient ovarian cells].
Essential differences in the architecture of the chromosomes between the 7 species of Anopheles maculipennis complex are found. The system of chromosomes' attachment to the nuclear envelope is invariant within particular species, each of the species studied, together with homosequential A. maculipennis and A. subalpinus differing one from another. The spatial organization of nutrse ovarian cell chromosomes in experimental hybrids (A. maculipennis X A. subalpinus and A. sacharovi X A. matrinius) shows species-specificity pattern of parental species. Thus, the spatial organization of interphase nucleus is the invariant species sign, and from the author's point of view, this phenomenon is due to penetration of new type mutations--systemic mutations (according to Richard Goldschmidt), directly connected with speciation.
