Figure 1 .
Frequency histograms of hybridization values when hybridized with N. vitripennis (Nv; gray) or N. giraulti (Ng; white) control DNA. The Y-axis shows the number of markers which produced the relevant hybridization values of the 20,551 total markers. Hybridization values > 0 indicate greater hybridization to the N. vitripennis oligo, whereas values < 0 indicate greater hybridization to the N. giraulti oligo. Only a small fraction of markers produce greater hybridization to the alternate species oligo when hybridized with control DNA.
