Development of Single Nucleotide Polymorphism (SNP) Markers for Rapid, Inexpensive, and Standardized Identification of Pallid (Scaphirhynchus albus) and Shovelnose (S. platorynchus) Sturgeon Larvae

The purpose of this project was to develop inexpensive, standardized, and high throughput Single Nucleotide Polymorphism (SNP) markers that discriminate between pallid (Scaphirhynchus albus) and shovelnose (S. platorynchus) sturgeon for use as a larval identification tool. A total of 67 polymorphic...

A total of 67 polymorphic sites was identified in DNA sequences from three genes: Recombination Activating Gene-1, Beta Actin, and Beta-2-Microglobulin.
