Electrophoresis method was used to analyze the genetic structure of four experimental Drosophila populations (the control one and those with 5, 10 and 15% of ethanol in the nutrient medium) with initial frequency of AdhF = 0.5 for 50 monitoring generations. It was established that F and S alleles had different selective values. Natural selection favoured the F-allele. Addition of ethanol to the nutrient medium increased the selection intensity in the first 15 generations but did not change the relative adaptability of three genotypes. This caused a similarity of genetic structure in experimental populations during 50 generations.
