Potamotrygon motoro and Potamotrygon falkneri, stingrays raw sequence reads. Potamotrygon

identify and validate a set of SNP markers in pure populations of P. motoro and P. falkneri for their application in further studies to examine the population genetic structure and patterns of invasion/colonization; and ii) identify a set of diagnostic SNP markers for each species P. motoro and P. falkneri to detect and examine the patterns of hybridization between them.
