[Autonomy of association frequencies of telomeric regions in salivary gland chromosomes during interspecific hybridization].

The study of association frequency and combination of salivary gland chromosomes participating in telomeric associations in interspecific hybrids between related species of "virilis" group of Drosophila (D. virilis, D. texana and D. imeretensis Sokolov) enables to conclude that each homologous chromosome behaves as an individual unit in the process. Besides, it is shown that the frequency of association of an autonomous property of telomere, i. e. it is not changed in interspecific hybrids in comparison with parental species.
