Facts

- Although approximately 40% of the samples have haplotypes of unequivocal European origin. (11295824)

- An equivalent number of samples have a single binary haplotype that is also observed in Indonesia and New Guinea, indicative of common indigenous Melanesian ancestry. (11295824)

- The balance of the lineages has either typical East Asian signatures or alternative compositions consistent with their affinity to Melanesia or New Guinea. (11295824)

- Molecular analysis of mtDNA variation confirms the presence of a single predominant characteristic Southeast Asian (9-bp deletion in the Region V) lineage. (11295824)

- The Y-chromosome results support a pattern of complex interrelationships between Southeast Asia, Melanesia, and Polynesia, in contrast to mtDNA and linguistic data, which uphold a rapid and homogeneous Austronesian expansion. (11295824)

- The Y-chromosome data highlight a distinctive gender-modulated pattern of differential gene flow in the history of Polynesia. (11295824)
