Alignment of Lmx homeodomain sequence. Alignment of the Lmx genes homeodomain region, showing the conservation of two intervening introns labeled (0). Mnemiopsis's first intron position is 3' to the highly conserved position in other taxa. The second intron position is shared with other taxa, but not with the anthozoan Nematostella. Dm,Drosophila Melanogaster; Hs,Homo sapiens; Ml, Mnemiopsis leidyi; Nv,Nematostella vectensis; Ta,Trichoplax adhaerens.
