Neighbor-Joining Analyses of a 298 base pair fragment of the mtDNA CR D-loop.
Numbers above the branches indicate bootstrap values inferred from 1000 replicates. Branches corresponding to partitions reproduced in less than 50% bootstrap replicates were collapsed. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree.

Principal Components I and II separated juveniles of yellowfin (Upper; n = 43) and bigeye (Lower; n = 5) tunas and comparison of their liver morphologies; yellowfin (A. Itano, 2005 and B. Pedrosa-Gerasmio et al., 2011) and bigeye tuna (C. Itano, 2005 and D. Pedrosa-Gerasmio et al., 2011).
