Results of ASE analyses. (A) Numbers of genes showing cis-regulatory divergence between highland and lowland populations from Mexico and South America and common genes detected in both continents. (B) Correlation of estimated highland effects between Mexican and South American populations for all genes measured for ASE and a subset of 20 genes showing evidence of convergent evolution (highlighted in red). (C) ASE values of 8 of the 20 convergent genes in the Mexican Highland (ML), Mexican Lowland (ML), South American Highland (SA), and South American Lowland (SL) populations. The 8 genes were selected based on a threshold of >10 SNPs from the landrace parents in each of the 20 convergent genes. (D) PC analysis of the landraces based on SNPs called from the whole-genome sequencing data for each of eight genes with more than ten SNPs.
