Fig. 4From: Phlebotomus papatasi SP15: mRNA expression variability and amino acid sequence polymorphisms of field populationsSliding window analysis. Omega values (ω) were plotted for every 15 codons in the PpSP15 sequence of PPAW, PPJS, PPJM, and for all the sequences together in a single group (All). The last window (9th) presented a single codon. Values above one are indicative of positive selectionBack to article page
