Datafile 1
Title: "Dipturus_batis_DArT_genotypes_genepop.txt"
Description: Genotype data for 503 individuals of blue skate (Dipturus batis), in GenePop format, at 6,350 single nucleotide polymophisms (SNPs).
One row per individual (sample_ID), two alleles per locus represented by three characters each (e.g. 001002). Loci with missing data are recorded as
000000. Information on each of the 503 samples is provided in Datafile 2.
