Phylogenetic relationships amongst the T . californicus GOT1p1 / GOT1p2 paralogs. The tree is the 50% majority rule consensus tree of 16 most parsimonious trees obtained by using either (A) the first portion of the gene (1–923 bp) or (B) the second portion of the gene (924–1206). Numbers on the branches give the boostrap values obtained from 10 000 replicate bootstrap searches using the parsimony criterion. The tree was rooted using the putative ortholog ACO15246 cytAAT from Caligus clemensi. The GOT1p2 haplotypes in the SD and LJS populations that appear to have been converted by the GOT1p1 sequence in the end section are highlighted.
