Additional file 5 Fig. S2. A-F indicate the SNP sites that could be accurately classified by the default parameters of GenomeStudio (those with the first and second patterns (Fig. S2A, B). All formed a single cluster (AA, 00, 00; 00, 00, BB), representing a monomorphic locus. Those with the third and fourth patterns (Fig. S2C, D, E, F) were markers that showed three (AA, AB, AB) and two (AA, 00, BB; AA, AB, 00) clearly definable clusters.
