Autosomal DNA of Argentine Mennonites

http://www.nature.com/articles/srep36392


Methods
Sampling
A total of 27 saliva samples were recruited on Oragene DNA collection kits (DNAgenotek) from individuals belonging to the Mennonite congregation of ‘La Nueva Esperanza’ (La Pampa, Argentina). Non related males from this DNA collection were previously analyzed for Y-chromosome markers.

Admixture analysis of Mennonite genomic profiles
Admixture analysis was carried out using a selection of 1000G population sets that represent the main continental ancestries. With the selected populations, K = 4 yielded the analysis with the lowest cross validation value; this analysis classifies profiles into four main groups that coincide with Europeans, Native Americans (represented here by Peruvians), East Asians, and Sub-Saharan Africans (Fig. 3A). This analysis allocates most of the Mennonite genomic variation (99.7% on average) to European ancestry.

(A) Analysis of admixture of Mennonites using ADMIXTURE. The bar-plot represents individual ancestries in reference populations and Mennonites. The analysis was carried out using the unsupervised clustering algorithm implemented in ADMIXTURE and considering the run with the lowest cross validation value. (B) Genomic (chromosome) ancestry mosaic for one Mennonite (#MEN01) using PCAdmix (reference populations: CEU, YRI, CHB, PEL). (C) Admixture proportions of Mennonites using PCAdmix (reference populations: CEU, YRI, CHB, PEL).

They are similar to White Americans 99.7% euro on average and mostly NE

Which towns/villages in Argentina have the highest presence of North European descended people?

Which towns/villages in Argentina have the highest presence of North European descended people?

La Pampa, Entre Rios and Misiones are the most German/Russian/Ukranian. Buenos Aires, Santa Fe and Cordoba have a little of everything.

This maps were made with a surnames database and the results are very accurate, but it doesent take into account Swiss/Austrian surnames which were pretty important in Argentina

Have any of these Mennonite genomes been uploaded to GEDmatch?

[Argentano]

How this people look. It seems they are mostly dutch

I dont know but their result is probably the same as that of a central european


The historical routes followed by Mennonite communities once they arrived to America from European countries exposed them to population scenarios that favored conditions for admixture with locals of African and Native American ancestry. Our data indicate however that the variation observed in Mennonites is virtually of 100% European ancestry. The Native American ancestry identified by ADMIXTURE and PCAdmix, apart from being very low, is most likely due to the presence of European component in the Native American populations used as references (see barplot of PEL in Fig. 3). In fact, admixture and PCAdmix analysis using other reference Native American populations, e.g. Aymara and Quechua samples from Reich et al.20, corroborate a virtually 0% Native American component in the genome of Mennonites (Figure S2). Therefore, this residual non-European ancestry cannot be considered to be real. The results obtained from the D-statistics (f3 and f4-tests) corroborate the lack of admixture between Argentinean Mennonite profiles and African and/or Native American variation.


Historical records indicate that pioneers of the Argentinean Mennonite community came from Chostitza and ultimately Central Europe, pointing to the Netherlands as the core of the original Mennonite diaspora

[Enflamme]

They seem to be contaminated by Nordo-Asian blood. :p

[Mariusz97]

As expected.

[Rethel]

Mennonites - the future of South America :laugh:

[Argentano]

They seem to be contaminated by Nordo-Asian blood. :p

Asian? the study says their 0.3% non euro is probably just noise

Until second half of 1940s in my town was a monnonite collony also :)
Probably one of them was still alive in 1970/80s so obviously they
should be still here, but live like a normal people...

Based on the findings of this research, Argentine Mennonites are whiter than your typical Non-Hispanic European American white.

It would be nice to see their GEDmatch results.

I think all Mennonites in South America are ultimately descended from Vistula Delta Mennonites?:

I descend from PA Dutch Mennonites.
