Using the method of Nei and Gojobori (22) and corrected for multiple substitutions according to ref. 23, values represent mean ± SE. Deletions and stop codon [in the case of the Su(Ste) sequence] were not included in pairwise comparisons. The source D. melanogaster sequences for comparison is as follows: βCK2 sequence (GeneBank accession no. U52952U52952), Su(Ste) sequence [61.2 copy (15)], euchromatic Stellate sequence [Ste eu; pSX1.3 (12)], and heterochromatic Stellate sequence [Ste het; Ste1 copy (13)]. 

^*For this gene pair, corrected synonymous divergence was calculated only at 4-fold degenerate sites.
