[Change in the genetic structure of an experimental population of Drosophila by electrophoretic locus under the effect of ecological conditions].

Dynamics of the genetic structure of experimental Drosophila populations being kept over 50 generations at 25 and 17 degrees C6 and on the medium with ethanol (12%) was studied. In all experimental populations alteration in allele frequencies of Adh, Gpdh, Hex and Est-6 loci took place in the first 20-25 generations on monitoring under the influence of the temperature and ethanol. Later on, an equilibrium relation between allele frequencies will be established.
