Table 2 Gene-wide tests of positive selection and McDonald-Kreitman test. A summary of P-values obtained for selection tests is shown for each gene. Results for McDonald-Kreitman test are shown for the whole gene as well as for each domain (Cytoplasmic, transmembrane or extracellular) (See Methods for abbreviations)

From: Positive selection at sites of chemosensory genes is associated with the recent divergence and local ecological adaptation in cactophilic Drosophila

  1. Significant and marginally significant values after FDR correction are in bold
  2. a This test showed positive selection specific to D. mojavensis lineage
  3. b This test was also significant for pairwise comparisons using D. mojavensis populations (SON and BAJ) and D. arizonae but not with ancestral D. navojoa outgroup (Additional file 1: Table S5)
  4. c This test was also significant for pairwise comparisons using D. mojavensis populations (SON, BAJ and CAT) and D. arizonae as well as ancestral D. navojoa outgroup (Additional file 1: Table S5)
  5. MKTotal: McDonald-Kreitman test for whole gene
  6. MKCyto: McDonald-Kreitman test for cytoplasmic domain
