Corsica

Facts

- Pronounced differences were observed between Sardinia, Corsica and Sicily as well as in the percentages of haplotypes previously shown to have distinctive patterns of continental phylogeography. (12772214)

- 60% of the Sicilian haplotypes are also prevalent in Southern Italy and Greece. (12772214)

- The Corsican sample had elevated levels of alternative haplotypes common in Northern Italy. (12772214)

- Sardinia showed a haplotype ratio similar to that observed in Corsica, but with a remarkable difference in the presence of a lineage defined by marker yM26, which approaches 35% in Sardinia but seems absent in Corsica. (12772214)

- Although geographically adjacent, the data suggest different colonization histories and a minimal amount of recent gene flow between them. (12772214)

- Studies identify possible ancestral continental sources of the various island populations and underscore the influence of founder effect and genetic drift. (12772214)

- The Y-chromosome data are consistent with comparable mtDNA data at the RFLP haplogroup level of resolution, as well as linguistic and historic knowledge. (12772214)
