Genetic varation was analyzed in populations of the paedogenic salamander Cryptobranchus alleganiensis throughout its range. An exceptionally high degree of homozygosity was observed at 24 genetic loci with most populations monomorphic at all loci. No major geographical variation was observed throughout the range of this species despite the fact that it occurs in a number of isolated drainage systems.
