Ng. Kan et al., GENOMIC POLYMORPHISM OF MINI-SATELLITE AND MICROSATELLITE LOCI OF THEPARTHENOGENIC LACERTA-DAHLI REVEALED BY DNA-FINGERPRINTING, Molecular biology, 32(5), 1998, pp. 672-678
The variability of mini- and microsatellite DNAs among the individuals
of the parthenogenic Caucasian rock lizard, Lacerta dahli, from popul
ations of Armenia was studied by multiloci DNA fingerprinting. The DNA
fingerprints of all specimens of the parthenospecies appeared to be p
ractically identical (species-specific), whereas those of the biparent
al species, L. raddei, proved to be individual-specific, Some of the m
ini- and microsatellite loci of parthenogenic animals revealed genetic
heterogeneity. Quantitative estimates of the genetic variability of m
ini- and microsatellite DNA fragments, such as the mean index of simil
arity (S) and heterozygosity (H), for parthenogenic lizards were 0.967
and 0.025, respectively, whereas in bisexual species they were simila
r to those observed in other outbreeding populations (S = 0.38 and H =
0.695). Computer analysis of 1561 marker fragments of parthenogenic l
izard DNAs discerned 12 DNA fingerprinting variants differing in 1-14
fragments. The data on the genetic variability of mini- and microsatte
lite loci of L, dahli may illustrate the process of spontaneous mutage
nesis and the initial stage of intraspecies differentiation in natural
populations of parthenogenic species.
