From: The role of selection in the evolution of marine turtles mitogenomes
Natural selection strength and the ratio of non-synonymous to synonymous substitutions (ω) calculated with two-ratio model in codeML for the 13 protein-coding mitochondrial genes (dataset III) of marine (Chelonioidea clade) and non-marine chelonians (all other chelonian clades). Genes in which the two-model fits better to the data (p < 0.05) are marked with an asterisk and were estimated with the two-ratio branch model in the PAML program. Gene names in bold represent genes with significant intensified selection on marine turtles detected by RELAX (p < 0.05).
