Figure 8From: Evidence for GC-biased gene conversion as a driver of between-lineage differences in avian base compositionGC3 is not at equilibrium in the majority of avian species. For the majority of lineages, GC3* exceeds GC3. As an exception the ostrich, Struthio camelus, shows no evidence of increasing GC content (GC3* = 0.4645; GC3 = 0.4666).Back to article page
