The most significant allelic frequency divergence found in this study between feral Andean horses and the comparison group within the TENM2 gene. A The arrangement of TENM2 genes from different species is shown from the UCSC browser along with the –log (p-value) for individual SNPs in the region. The green line represents genome wide significance. Linkage disequilibrium between adjacent SNPs (D’) is shown the browser graph. B shows the Fst nalysis of Chromosome 14 with the region of TEMN2 indicated (arrow). The green dotted line represents 2 standard deviations from the mean Fst value for chromosome 14.
