The presented p-values are corrected using the Bonferroni adjustment. p-values colored in red represent statistically non-significant differences between the average log GC ratios of the compared genes. Pairwise comparisons for the sw1, sw2 and lw opsins are highlighted in grey. (PDF 27 kb) 2015-10-06 05:00:00 Opsin Vision Birds Gene loss Pseudogenization Co-evolution Plumage coloration
