Table 4 Likelihood ratio tests (LRTs) to determine whether foreground ω estimates from the ‘CmC αβ MVR & β T ’ model significantly differ from ω = 1

From: Complex patterns of divergence among green-sensitive (RH2a) African cichlid opsins revealed by Clade model analyses

Foreground partition Unconstrained ω estimate lnL with constraint ω = 1 P-value
αβMVR (RH2aα and non-Tanganyikan RH2aβ branches) 1.0919 −3774.0580 0.7166
βT (Tanganyikan RH2aβ branches) 2.6122 −3777.2771 0.0104
  1. Both LRTs have 1 degree of freedom.
