Fifty unrelated Basque males from southwest Idaho were typed for the 17 Y-STR loci in the Yfiler multiplex kit (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, YGATA_H4.1 and DYS385a/b). A total of 42 haplotypes were identified, with no more than two individuals sharing a single haplotype. The haplotype diversity (HD) was 0.9935, and gene diversity (D) over loci was 0.457 ± 0.137. The Idaho Basque population was compared to the source population from the Basque autonomous region of Northern Spain and Southern France, as well as a US Caucasian population. The haplotype diversity for the immigrant Basque sample is within 0.4% of the haplotype diversity of the European Basques (0.9903); thus the power of discrimination is similar for each population. The Idaho Basque population has less diversity in 9 out of 16 loci (considering DYS385a/b together) and 3% less diversity across all loci, compared to the European Basque population. A multi-dimensional scaling analysis (MDS) was created using pairwise RST values to compare the Idaho Basques to other populations. Based upon RST and FST measures, no significant differentiation was found between the Idaho and source European Basque population.
