Hamming Distance matrix illustrating proportional differences across all analyzed adults using only the three most sex-linked SNP loci. Values closer to zero (blue) signify high similarity whereas values closer to one (yellow) are more dissimilar across the 13 loci. Colored regions at the top and at the left correspond to source ponds. At these three loci, all females show perfect concordance between genotypic and phenotypic sex. Most males also show perfect concordance between genotypic and phenotypic sex. Five males are discordant at only one of three loci
