Table 2. Summary of four Glossina chemosensory gene loci identified to have signatures of positive selection.
Selection analysis was performed using HyPhy package using MEME and PARRIS and compared with PAML –codeml using the M8-M8a model. lnL M8 is the likelihood of the experimental model (M8).

lnL M8a is the likelihood of the null model (M8a), ΔLRT is the Likelihood Ratio Test = 2*(lnL M8- lnL M8a), w1M8 is the ratio of non-synonymous to synonymous mutations (dN/dS) predicted under M8 model/and p-value is the statistical measure of significance.
