A fruit fly, Drosophila melanogaster, is widely used as a model to study how living organisms adapt to environmental changes and inherit particular characteristics. Advanced methods of the transcriptome analysis allow the research of this model object at a new level of description of all active genes in this organism.

The transcriptome analysis of several Drosophila melanogaster lab strains, an indispensable preliminary stage for their usage in further radiobiological studies, made it possible to reveal intriguing facts and regularities in cultivating the Drosophila melanogaster strains over 6000—10000 generations without natural selection. The findings were published by the Molecular Genetics Group in the Ecology and Evolution (Q1). At the seminar, the newly obtained results and prospects of further studies were reviewed.
