The Lewontin-Krakauer test for selective neutrality of polymorphisms was applied to temporal variation in gene frequency at five electrophoretic loci in each of four fluctuating vole populations over a three-year period. The results indicate that changes in gene frequencies were primarily due to nonselective forces.
