Figure 4From: K r /K c but not d N /d S correlates positively with body mass in birds, raising implications for inferring lineage-specific selectiond N / d S vs mass for high- and low-heterogeneity orthologues. Sequences with high and low between-species variation in GC3 show a negative correlation between d N /d S and body mass (shown for the data set of 48 species).Back to article page
