Chromosomal and molecular perspectives on Potamotrygon motoro (Müller & Henle, 1841) from central Amazon

Genome
Cytogenetic studies on Potamotrygon motoro (Müller & Henle, 1841) are limited to classical cytogenetic techniques, but they do reveal great karyotypic variation. The main differences are related to the karyotypic formula and the absence/presence of sex chromosome systems.
