dN/dS ratio of haplochromines compared to non-haplochromines in two segments of kita. The sliding window analysis with DNASP did not detect a dN/dS > 1 in the extracellular domain (a) or in the intracellular domain (b) of kita. See Figure 4b for the same analysis in csf1ra and the Methods section for details of the analysis.
