From: The role of selection in the evolution of marine turtles mitogenomes

Signatures of selection for each codon for 13 mtDNA genes using SLAC method within the Chelonioidea phylogeny (dataset IV). Positive (positive values) and negative selection (negative values) are shown. ND6 is transcribed from the light strand. * is the third codon position of ND5 found under positive selection by FUBAR and MEME.
