Likelihood ratio tests of branch-site models on <i>C3</i> genes.

<p>Note: np number of parameters, ln<i>L</i> ln[likelihood] value, 2Δ(ln<i>L</i>) 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 <i>C3-2</i>, stickleback5 the three-spined stickleback <i>C3-5</i>.The <i>P</i>-values<0.01 are shown in boldface. The human <i>C3</i> sequence was used as reference to mark the positions of the positive sites in all cases. Sites with the <i>P</i>-values<0.05 are shown and those with <i>P</i>-values<0.01 are in boldface.
