Ologous groups while light grey boxes indicate gene linkage. Bootstrap values below 70 have been removed. Only two Lbx proteins are included as the third sequence (found on scaffold 8483) is incomplete. Note that the Lbx sequences separate into two clear groups, Lbx1 and Lbx2, which are supported by bootstrap values of 79 and 83 (boxed), respectively. The chicken protein previously denoted as Lbx3 [18], the zebrafish protein previously denoted as Lbx1 [14] and one of the fugu, , stickleback and medaka sequences group with mammalian Lbx2 sequences. The two novel zebrafish Lbx sequences and the remaining teleost sequences group with mammalian, chicken and frog Lbx1. The tree shows significantly longer branch lengths for the Lbx2 proteins indicating that these sequences may be evolving at a quicker rate than the Lbx1 proteins.
