Latin American genetic studies [official archive]

I wish it broke down the African also. Dominicans should, in which case, have a lot of Senegambian ancestry but I have no idea what Puerto Ricans would get.

Probably a good amount, it's very interesting to me that Caribbean Hispanics have almost no Basque ancestry while around 1/4 of the (small) European ancestry in Peruvians is basque in origin.

A lot of Basques emigrated to Chile due to the similar weather and geographic conditions.. I reckon many Basques wouldn't have had much fun in such a tropical place like the Caribbean...

I agree totally, I actually think that these regional breakdowns are the most interesting part of this study. It's interesting to see how each country varies slightly in terms of where in Europe their ancestors came from. The study also draws attention to the higher Basque scores among Mexicans and their small British ancestry. The first is the legacy of Basque immigration to Mexico, and the second a result of contact with the US (according to their intepetation).

The results are wrong. Basque made up to 6-8% of the settlers in Mexico but are only 2.19% of the genetic contribution.
And Basque made up to 15-25% of the settlers in Northern Mexico. These states of Sinaloa,Durango,Zacatecas,Sonora made the states of Nueva Vizcaya. 1.43% British in Mexicans is a lie. Americans nor British settled in Mexico ,maybe 10,000 .
Their is American retirees but they don't have families in Mexico.

The Basque contribution is 2.19% of the total genome, which means that it it is 4.59% of the European contribution. That number is pretty consistent with 6-8% of the European immigrants to Mexico being Basque. I also think, like Sikeliot said, that the British scores could reflect Northern Spanish and Basque ancestry because of the ancient connections between those two groups.

The so called British in Mexicans is coming from Northern Spanish and Basque. Mexico recieved plenty of Northern Spaniards except Gallegos. Their is no history of British even less of white Americans settling in Mexico and contributing to the Mexican gene pool.

I found this in the supplement section, I think they are the numbers for each sample.

Wow! Only 68 samples for Mexico for a country of 118 million. I wouldn't take these results so serious for Mexico.

They look accurate for the peasant class though.

The "South Italian" and "Greek" in the Caribbean Hispanic groups but not in Mexico implies to me that the Spanish input in the Caribbean has a) more Sephardi Jewish mixed in with it, b) more Canarian or North African influence, or c) a combination of the two.

B..

The Carribean countries recieved alot of Canarians. Carribean Latinos don't score more Ashkenazi than Mexicans.

Not really. Southern Mexicans peasant class won't even score 25% Iberian.
