Table 1 Discovery and validation criterion for differentiated genomic regions

F _ST Region with an over-representation of SNPs possessing high F_ST values relative to the genome-wide distribution of F_ST scores

Regional evidence in the top 0.1% of the genome-wide distribution, in which:

Discovered region should contain evidence found in the top 1% of the genome-wide distribution

- Regions are defined by window sizes of 100 kb and 500 kb;

- Evidence is defined by the P-value of the exact Binomial test for the proportion of SNPs with F_ST in the top 1st percentile (100 kb) or 0.1st percentile (500 kb) respectively of the genome-wide distribution score

Differential iHS signals for GIH and INS

At least one SNP with normalized iHS score in the top 0.19% of the genome-wide distribution in one population, but not present in the top 1% of the genome-wide distribution in the other population

At least one SNP in the discovered region should have an iHS score in the top 1% of the genome-wide distribution, but absent in the top 1% of genome-wide distribution of iHS scores in the second population

XP-EHH between GIH and INS

Normalized XP-EHH scores should lie in the top 0.01% of the genome-wide distribution

At least one SNP in the discovered region should lie in the top 0.5% of the genome-wide distribution of the normalized XP-EHH scores
