Figure 6

Sliding window analysis of positive selection unigenes in A. tequilana (red) and A. sisalana (black) compared with A. deserti, respectively. The window size is 30 bp, with a step size of 6 bp. The x-axis denotes the nucleotide position. The y-axis denotes the Ka/Ks ratio. The gaps represent Ka/Ks ratios that could not be computed.
