Snegin E. A. Analysis of Genetic Variability in Populations of a Terrestrial Snail Chondrula tridens Mьll. (Gastropoda, Pulmonata), Based on the RAPD and ISSR Markers // Russian Journal of Genetics: Applied Research, 2014, Vol. 4, No. 5, pp. 444–454.
In this study we examined evolutionary processes in the populations of small mobile animal spe
cies, the terrestrial mollusks Chondrula tridens Müll. (Ch. tridens) in the urbanized landscape. We applied
PCR methodology, using the RAPD and ISSR DNA markers, to define the genetic structure in the Ch. tridens
populations, inhabiting the MidRussian Upland. Analysis of the obtained DNA patterns uncovered the
presence of both polymorphic and monomorphic alleles. Based on this data, we defined the levels of genetic
variability in the studied Ch. tridens populations, and determined the factors affecting formation of the pop
ulation’s gene pool in this species. We present our conclusions on the genome structure and gene pool distri
bution in the populations of the Ch. tridens in the urbanized landscape.
