Inter- and intrapopulational genetic variability of Tityus serrulatus (Scorpiones, Buthidae)

Acta Tropica, 2009
In Brazil, there are near 20 genera and almost 120 species of scorpions of which 95% reproduce sexually. Parthenogenetic reproduction, however, may also take place. To gain insight into useful molecular markers in parthenogenetic scorpion species, we studied DNA polymorphism using two molecular approaches: simple sequence repeat anchored polymerase ...
