Data From: Strong genetic structure among populations of the tick Ixodes ricinus across its range

The dataset consists of individual genotypes of 497 samples obtained from 125 biallelic SNP loci in 28 populations, from 20 countries. The dataset is formated for use in STRUCTURE (Pritchard et al. 2000), with one row for sample. The first column has individuals IDs, the second column has population unique IDs, and genotypes are presented in the subsequent columns. Missing data is coded as -9.Individual sample codes are as follow: population code as in the paper, followed by a an unique number. Codes for each base: A - 1 / T - 2 / G - 3 / C - 4Other details are presented in the Material and Methods section of the associated article.
