Autores: Echeverrigaray,Sergio; Grazziotin,Gilberto; Grazziotin,Felipe; Agostini,Gustavo.
The present work was made to determine the suitability of RAPD analysis for the identification of specimens of two subspecies of South American rattlesnakes (Crotalus durissus terrificus and Crotalus durissus collilineatus). The 11 arbitrary primer sequence tested amplified a total of 161 bands, of which 31% were polymorphics when compared with Crotalus specimens. The combining results from different primers allowed the identification of all the specimens under analysis. Several characteristic bands of each subspecies were identified. Dendrogram, based on RAPD markers, show three groups that corresponded to the subspecies of Crotalus, and to Bothrops jararaca specimen.

Genetic relationships among species of the genus Bothrops based on RAPD markers
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Grazziotin,Felipe; Echeverrigaray,Sergio.
The genetic relationships among 11 species of Bothrops found in Brazil were determined using random amplified fragment (RAPD) information. A total of 239 amplified bands were scored using 20 aleatory primers. Most of the bands (88.7%) were polymorphic. Phylogenetic analysis of the data determined three similarity groups within Bothrops: Group I- B. alternatus, B. neuwiedi, B. cotiara, and B. jararacusu; Group II- B. insularis, B. jararaca, and B. erythromelas; and Group III- B. moojeni, B. leucurus, and B. atrox. These groups coincided with those obtained by other methods, indicating that RAPD's could be a useful tool for the evaluation of genetic relationships at the interspecific level.
