  1. Calculations are based on alignments spanning the first through the sixth transmembrane domain. The n2 value indicates number of twofold degenerate amino acids, c2 indicates the number of twofold degenerate amino acids with conserved third-position nucleotides, and f2 signifies the percentage of conserved third-position nucleotides at these positions (that is, c2/n2). Interspecies orthologs between fly and mosquito (and between mouse and human, near top) are shown in bold, and intraspecies paralogs are shown in underline and italics. Comparisons of lower f2 values (for example, 0.55 vs 0.50) are not as meaningful (with respect to estimating divergence dates) as higher-value comparisons owing to equilibration within the lower ranges.
