| Molecular genetic identification of a Mexican Onza specimen as a Puma (Puma concolor) | |
| 1996 Interdisciplinary Journal of the International Society of Cryptozoology (12): 42-49 | |
Tissue samples from an alleged Mexican Onza, shot in the western Sierra Madre in 1986, were subjected to several biochemical assays in an attempt to determine the specimen's relationship to felid species of North America. Protein analyses included isoenzyme electrophoresis and albumin isoelectric focusing. Mitochondrial DNA was assayed for restriction fragment lengths with 28 restriction enzymes, and the ND5 gene was sequenced. The resulting protein and mitochondrial DNA characteristics of the Onza were indistinguishable from those of North American pumas. |
