Table 1 Super-haplogroups, haplogroups, sub-haplogroups, and private Sardinian-Corsican clades.

Here the average number of SNPs defining each class is shown in our 1209 samples. The asterisk (*) denotes that the average number of SNPs for haplogroups A and E cannot be determined with precision because of the lack in our sample of individuals belonging to haplogroups B, C, and D. Consequently, the number reported here is an overestimate. The Sardinian samples are progressively numbered from 1 to 1204, and the non-Sardinian samples are labeled as follows: O, Ötzi; T, Tuscan; B, Basque; C, Corsican; I, northern Italian. The clades containing only private Sardinian SNPs are indicated in Greek letters (progressively from α to δ within each haplogroup).
