[Variability of GATA-microsatellite DNA in populations of the parthenogenetic species of lizard Lacerta unisexualis Darevsky].

Multilocus DNA fingerprinting was used to analyze the genome variation of mini- and microsatellite DNA regions in parthenogenetic Caucasian rock lizard Lacerta unisexualis. The DNA fingerprints obtained with probe M13 were nearly identical in all populations examined (the average similarity index S = 0.992). The fingerprints obtained with probe (GATA)4 varied (S = 0.862). Polymorphic fragments were assumed to correspond to allelic variants of genetically unstable GATA loci. Comparison of the fingerprints of animals from four geographically isolated populations revealed several population-specific GATA microsatellite markers. Based on their distribution among the populations, the corresponding alleles were assumed to originate from a common ancestral allele.
