Genepop formatted file containing genotypes from the 6,254 filtered SNPs and 286 individuals with >80% genotyping rate used in this study. SNP names are radtag_snp position i.e. a SNP named 12_46 would be on radtag number 12 and the SNP would be at position 46 in the tag. Population abbreviations are identical to those in Table S1 of the publication.
