Abstract:
The randomly amplified P = ploymorphic DNA (RAPD) method was employed to screen the genetic markers in the genomic DNA of 10 species of the snakes in Colubridae.The cluster analyses for the molecular genetic bata of the snakes indicated that: 1.There was a genetic variability among the individuals of each species.But the differences detected by proportion of shared frayments between the species were obviously larger than those within a species.Randomly sampled individuals, therefore, could be used in the study on the phylogenetis relationship among different species.2.Elaphe was a higily differentiated genus.Among the 5 species analyzed in this study.E.mandarinus was closely related to E.rufodorsata.and the two species could be grouped together.But the relationship among the other 3 species was still a question.3.Among the 6 genera of Colubridae, Elaphe, Zaocys and Ptyas were closely related.while Rhabophis and Sinonatrin had a closer relationship to Dinodon.The latter three probably represented a pnmitive group in the family.
