Maori

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#)
