Recently introduced Y-SNPs improve the resolution within Y-chromosome haplogroup R1b in a central European population sample (Tyrol, Austria)

Abstract

Three recently described Y-chromosome single nucleotide polymorphisms (Y-SNPs) were typed in a sample of 135 men from Tyrol (Austria). These SNPs define sub-clades of haplogroup (hg) R1b. The derived states of U152 (hg R1b3h) U106 (R1b3i) and U198 (R1b3i1) were found within the Austrian R1b population sub-sample (N = 42) in 9 (21.4%), 25 (59.5%), and 1 (2.4%) individuals, respectively. Only 8 (19.0%) of the hg R1b Y-chromosomes remained unresolved. These novel SNPs proved to be promising tools for distinguishing R1b lineages in the evolutionary as well as in the forensic context. © 2008 Elsevier Ireland Ltd. All rights reserved.
