Lv. Frisman et al., Allozyme differentiation of the forms of the spotted souslik (Spermophilussuslicus Guld, 1770, Rodentia) with different chromosome sets, RUSS J GEN, 35(3), 1999, pp. 307-313
Eleven enzyme and four nonenzyme protein systems controlled by 25 loci were
electrophoretically analyzed in the allopatric karyotypic forms (2n = 34 a
nd 2n = 36) of the spotted souslik Spermophilus suslicus. Genetic variabili
ty and differentiation for the forms with different chromosome sets were es
timated. Two discriminative loci (Alb and Tf) for the studied chromosome fo
rms were found. The UPGMA dendrogram was constructed, which summarizes gene
tic (allozyme) relationships found for the forms of the spotted souslik wit
h different chromosome sets. Subdividing the species into two karyotypic fo
rms was shown to be followed by differentiating these forms at the allozyme
level.
