Parameter Ors Grs p-value Ors Grs p-value Ors Grs p-value
dN 0.094 0.146 0.004 0.103 0.152 0.005 0.089 0.141 0.001
dS 0.936 1.036 0.924 1.009 1.039 0.681 0.945 1.018 0.623
dN/dS 0.102 0.141 0.005 0.104 0.142 0.002 0.093 0.131 0.001
  1. Mean dN and dN/dS was greater for Grs suggesting that, overall, Grs were more divergent than Ors in all three species
