↵Number of sequences in the group.
↵ P-values in bold represent significant tests in which ω is inferred to be >1.0. P-values are Bonferroni corrected for the number of tests within a column and an experimental Type I error of 0.05.
↵ω is d _N:d _Sestimated under M8; P ₁ is the inferred proportion of positively selected sites.
↵Position locations are based on alignments with gaps. Underlined positions are those common to the results of the analyses of the complete and domain alignments.
