Fig. 4: Amino-acid polymorphisms in the adult βA and embryonic ɛ-globin genes (HBB and HBE, shown in red) are extreme outliers in genomic scans of allele-frequency differentiation between low- and high-altitude populations of speckled teal and yellow-billed pintail.

The histograms and box plots depict genome-wide distributions of SNP-specific FST and 99% upper quantiles based on the RAD-Seq survey of genomic polymorphism (speckled teal = 47,731 SNPs, yellow-billed pintails = 49,670 SNPs). Arrows indicate extreme outliers resulting in the labeled amino-acid replacements.
