Fig. 5: Maximum likelihood phylogeny for four sequenced Tigriopus species.
From: Genomic signatures of mitonuclear coevolution across populations of Tigriopus californicus

The tree was estimated in MEGA6 (ref. 73) from a concatenated alignment of 20 randomly selected genes, totalling 9,721 amino acid positions. Values above each branch show the number of genes detected to have significant positive selection following ‘branch-sites’ tests41 (total/mtDNA-interacting). SD, San Diego; SRQ, San Roque.
