The paper deals with carrying out molecular-genetic typing of populations of snail Lymnaea stagnalis from regions with a different ecological load (the lake Perstok and zatoka of the river Pripyat, Belarus). By means of interpopulation analysis of frequencies of RAPD-fragments, frequencies of zero alleles of RAPD-loci and genetic similarity index we established that these populations are genetically identical because there are no significant distinctions of genetic variability neither between individuals within a population, nor between populations. Results of the cluster analysis and the population analysis also have confirmed that populations of snails are genetically closely related. However the snail population of the lake Perstok is genetically more homogeneous.
