The letter sunder the black bars illustrate the dispensation orders below the upper panels (Disp:). The actual sequences detected by pyrosequencing are indicated below the lower panels (Seq:). The Y-axes represent the level of fluorescence emitted by the incorporation of a nucleotide base, and the X-axes represent the total number of bases added atthat time. The light gray areas show the pyrograms for the species differentiations in this cluster.
