Effects of genomic instability in populations of Drosophilae melanogaster from regions of Ukraine with different radiation impact factors

Abstract

Differences in the gonadal dysgenesis frequency as an indicator of the activation of mobile elements were revealed in F1-descendants of natural populations of Drosophіla melanogaster, selected from regions of different radiation impact. Under conditions of additional low-rate chronic irradiation in laboratory conditions for 10 generations, significant differences in changes in the level and dynamics of this indicator were established depending on the accumulated dose of Drosophila populations from the city of Netishin (Khmelnytskyi NPP) and Magarach city.
