Likelihood ratio tests of branch-site models on C3 genes.

Note: np number of parameters, lnL ln[likelihood] value, 2Δ(lnL) twice the difference of ln[likelihood] between the two models compared, vert, mam, OP, and Acan the ancestor branches of the vertebrates, mammals, ostariophysian together with protacanthopterygian fishes, and acanthopterygians fishes, respectively, examined in present study, seabass2 the seabass C3-2, stickleback5 the three-spined stickleback C3-5.The P-valuesC3 sequence was used as reference to mark the positions of the positive sites in all cases.
