Summary
Gene-enzyme variation was examined at a number of allozyme loci, in two natural populations of Daphnia pulex. Both quantitative and qualitative differences were uncovered between the two populations. Temporal studies of variation, at three polymorphic loci, in a permanent population from Saratoga Lake revealed considerable fluctuations in allele and genotype frequency. The possible forces at work to produce these fluctuations are discussed. Genetic evidence is presented supporting the contention that parthenogenesis in this species is ameiotic. No consistent pattern of excess heterozygosity was observed in D. pulex.
