^#Repeat-based elements are denoted by an r before the set name.
*Gene sets that were not different between the two alignments.
^Gene sets in the repeat-based alignment that were merged from two or more cDNA-based alignment sets.
^§A score of 1.5 indicates that changes in half of the nucleotides are nonsynonymous.
