Phylogenetic Tree from Scientific Research

Genic convergence site (Q550L) of rtf1 in fish species found below 3,000 m. The phylogenetic relationships on the left indicate the different habitat depth ranges of fish species using five colors. Above is the gene structure of rtf1, and on the right is the protein sequence alignment of rtf1 in 107 species. Mutant sites are marked in red for L and green for Q, with the shaded area highlighting species exhibiting the Q550L mutation. The size of amino acids above the alignment is proportional to their conservation across these species.
