Genotypic measures are given only for multi-locus genotypes. G0 refers to Simpson's diversity index of genotypes. Proportion of polymorphic pools are given with respect to alleles, not genotypes. Sample sizes were 49 pools for D. longispina and 77 pools for D. magna. “All” indicates the total across all loci and pools; “pool mean” indicates the average within a pool across all loci.
