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)
