Abstract:Introdution
Currently, there are 38 valid species of freshwater stingrays, and these belong to the subfamily Potamotrygoninae. However, cytogenetic information about this group is limited, with studies mainly using classical techniques, Giemsa and C-banding.
Methods
In this study, we used classical and molecular cytogenetic techniques (mapping of repetitive sequences 18S, 5S and SSRs) in order to investigate the karyotypic composition of P. schroederi and draw a parallel with the karyoevolutionary trends of t… Show more
