Sequence variation in the control region (D‐loop) of the mitochondrial DNA (mtDNA) was examined to assess the genetic distinctiveness of the shortjaw cisco ( Coregonus zenithicus ). Individuals from within the Great Lakes Basin as well as inland lakes outside the basin were sampled. DNA fragments containing the entire D‐loop were amplified by PCR from specimens of C. zenithicus and the related species C. artedi , C. hoyi , C. kiyi , and C. clupeaformis . DNA sequence analysis revealed high similarity within and among species and shared polymorphism for length variants. Based on this analysis, the shortjaw cisco is not genetically distinct from other cisco species.
