Summary
Analysis of gene frequencies at ten enzyme loci (six polymorphic) failed to produce any evidence that races exist in the frog Ranidella insignifera associated with the edaphic feature of sand and clay based ponds. Most polymorphic loci exhibited macrogeographic uniformity of allele frequencies but in no case had any one allele become fixed in any one population. Nor were there any alleles unique to sand populations only or to clay populations only. Genetic distance algorithms failed to show any intra-specific divergence intermediate between inter-population and inter-sibling species levels.
