dc.description.abstract | Aims. The purpose of investigation was to study the effect of acute irradiation by brake γ-quantums on the components of fi tness in Drosophila melanogaster Meig. Methods. The effect of acute γ-radiation at doses of 8 Gr, 16 Gr and 25 Gr on the fertility, the number of adults, the level of dominant lethal mutations (DLM) and life span of adults in the wild-type strain Oregon-R were investigated. Female adults in the age of 3 days were irradiated by brake gamma rays on the linear electron accelerator LEA-10. The dose rate was 0.4 Gr/sec. Results. Under the action of acute exposure brake γ-rays with increasing doses in the range of 8–25 Gr a decrease in egg production, increased longevity of adults in the F1 generation were found. DLM frequency increased in generation F1 and returned to the control values, or (at 25 Gr) decreased in the progeny F2 . The number of adults in the progeny was not changed. Conclusions. In accordance with the data obtained it can be concluded that the trends of K-strategy of selection in these conditions of exposure in Drosophila melanogaster were realized. Keywords: Drosophila melanogaster Meig., fi tness, egg production, life span, dominant lethal mutations. | uk_UA |
