  • Haplogroup B in New Zealand

    I joined the Genographic project, as am of Maori matriarchal descent as was keen to find out the research or info on this group . As they have only been in NZ for 800 years.
    I see that NZ is not on linked to haplogroup B migratory route on the map?

    I read on another site that the Mtdna line for maori seems to be from central asia. Whereas the male Y descent to be more Melanesian based?

    Is there any up to date info on the polynesian in particluar. I was hoping that this type of indepth research would be present in the project, and would be updated as it learns more?

    Will they publish new information on this group as it comes to hand? How do we otherwise find out how our participation aids researchers? The information received is more of a general line ( which does not reach New Zealand??)

    Haplogroup B in New Zealand

    Yes, they will publish new information as the project progresses. Take a look at the Human Journey article in the March 2006 National Geographic Magazine as well as the feature on the magazine's website ( I'm also Haplogroup B, and the online feature includes an article I wrote on finding my DNA cousins, one of whom is of Maori descent in New Zealand. It's called "Meet the Family." If the March issue is already down when you get this message. Just got to "Archive: Magazine" in the nav bar to retrieve it. I hope you enjoy the articles and will spread the word.

      Ina Clan - Haplogroup B

      Ina Clan - Haplogroup B

      Best link regarding mtDNA haplogroup B:

      A few excerpts (but go to the link!):

      Ina's clan is known to have populated not only North and South America, but the Pacific Islands and possibly Madagascar as well. Her name comes form the Polynesian mythological figure " Ina", who appears on the banknotes of Rarotonga in the Cook Islands riding on the back of a shark to the island Mangaia. She is representative of the "first woman" and is also often personified in the moon.


      After coming out of Africa, modern humans first spread to Asia following two main routes - a Southern one and a Northern one. The Southern one is represented by macro-haplogroup M which radiated some 30,000–57,600 yrs BP (before present) and is overwhelmingly present in India [1] and Eastern Asia where it possibly originated and expanded as haplogroups C, D, G, and others [2].

      The other major branch that left Africa, the Northern one, is represented by macro-haplogroup N. It has a lower bound of 43,000–53,000 yrs BP, and spread into at least three main clusters. The first cluster comprises haplogroups X and A, with only a shared mutation between them and different geographic distributions (A is widespread in Asia, X is mainly restricted to Europe). The second cluster groups minor haplogroups W, I, and N1b (each of which is present in low frequencies in Europe, the Near East, and the Caucasus). The last cluster radiated around 39,000–52,000 yrs BP and gave rise to four major ancestral clusters: Two of them, B and F, derive from N through a common ancestor with most Europeans - phylogenetic node R [3]. The others originated haplogroups J, T, H, V, K, and U, which expanded from the Near East-Caucasus area.

      Haplogroup B expanded from Central Asia to Eastern Asia, reaching Japan and the Southeastern Pacific Archipelagos. And, unlike previously believed, it is also found in some Siberian populations. From there, a substantial number of Ina's descendants then reached North America, either with the other colonists around 13,000 yrs BP via the Bering land bridge, or in a sea-borne colonization along the coast (or both).

      Today the highest frequency of Haplogroup B is among Polynesians (95%). It is present in Tibetans, Koreans, Japanese, and Mongolians, and is widely spread throughout Southern Siberian populations, although in low frequencies. It is also present, but in low frequencies, in many West Eurasian populations. (See Table at link.)

      Subclade B4a (the Pre-Polynesian motif) is very common in the Philippines:

      B4a - Pre-Polynesian motif - 189, 217, 261. Found in remote Oceania, Near Oceania, South East Asia, and a single Native American. (Hurles 2003). Related mtDNA types are highest in frequency in the corridor from Taiwan, south through the Philippines and east Indonesia. The highest diversity for these types is in Taiwan, which is "consistent with linguistic evidence of a Taiwanese origin for the proto-Polynesian expansion "throughout Oceania by way of Indonesia. (Melton 1995). This expansion is believed to have began about 5,500 yrs ago. (Redd 1995).
