Molecular basis of hemoglobin adaptation in the high-flying bar-headed goose
Fig 3
Trajectories of change in intrinsic Hb-O2 affinity (indexed by P50, torr) in each of six possible forward pathways that connect the ancestral ‘AncAnser’ genotype (GAP) and the wildtype genotype of bar-headed goose (SVA).
Derived amino acid states are indicated by red lettering. Error bars denote 95% confidence intervals.
