MAF, minor allele frequency; #, number; SNPs, single nucleotide polymorphisms; Ho, level of genetic variability in terms of observed heterozygosity; He, level of genetic variability in terms of expected heterozygosity; GSF, Guernsey Sea Farm.
a
Values were obtained by the analysis of the combined dataset, not the average of the individual populations.
b
Values represent the within-population average.
