Synopsis
Starch gel electrophoresis of the common shiner, Notropis cornutus, was used to determine if this species exhibits genotypic structuring. Specimens were collected from seven widespread localities representing three branches of a single river drainage. χ2 tests revealed no significant heterogeneity of Est-A electromorphs within or between localities except where physical barriers prevent contact. Therefore, schooling behavior of N. cornutus is not associated with significant genotypic structuring of this species.
