RNA-Seq identified SNPs that were further validated by Sanger sequencing in other individuals of the two lineages.

<p>Shaded boxes correspond to SNPs that Sanger sequencing failed to validate.</p

The list of genes involved in cellular energetics that were targeted in the current analysis.

<p>Genes involved in Oxidative Phosphorylation are also separated by Complex (Complexes I-V). Genes encoded by the mtDNA are presented as underlined.</p

RNA-seq analysis pipeline.

<p>Schematic representation of the bioinformatics pipeline used in RNA-Seq analysis and SNP detection in nuclear-encoded genes.</p

The rate of total and non-synonymous differentiating mutations, respectively, for the three energy producing procedures.

<p>In the OXPHOS, rates are also presented for each of the five complexes separately, distinguishing between nuclear and mtDNA-encoded genes.</p
