Latin American Whites Eurogenes K15 PCA

[Argentano]

Good job, bro. You post good work in relation to DNA. I like it.

The South Americans seem to plot near N. Italians. I think this is so because maybe that is the halfway point between Spain and central Italian, being Spanish and Italian is very common mixes.

I think I understand why white Cubans cluster near Portuguese. Iberian Spanish+Canarian Spanish should put them there.

As for Puerto Ricans, hmm, I wonder why they are just under N. Italy. It seems they clustered near Uruguayans. What is your opinion on that one? Maybe a couple percent Amerind influenced it? Hmm. Interesting.

If you look at ibericus k15 pca the canarians plot a little right to the spaniards so maybe that puerto rican position is related to that.

The brazilian and Argentine is position is related to Italian and other ancestries.

Thanks. Its very interesting to me as well, thats why i like to gather the gedmatch kits


Edit:With the puerto ricans i comit a mistake. I decided to do the white puerto rican because i had many puerto rican samples BUT the truth is that the whites in the puerto rican samples were just 2 or 3. So the puerto rican sample is not as good as i thought.

The Brazilian/Argentine/Cuban samples have around 70/80 whites each.

Wow, they are all over the place, from France to Spain, Portugal, Germany, Italy, Jews and the Balkans.

yes, normally the surnames had some kind of relationship with where they plot. Very interesting.

The ones near portugal have spanish surnames though.

Well remember that western Spaniards are more genetically similar to Portuguese than other Spaniards, so that may have something to do with it. I think in the case of the white Cubans, it is Iberian Spanish+Canarian Spanish that puts them near the Portuguese. But for the Argentines, these particular ones might be of western Spanish descent possibly, but that could be the case for the Cubans too. I guess it just depends on the circumstances.

As for the surname thing, that happens here in the US too. You could have someone with an English surname and they be half Italian and a quarter German. But they could also be mainly or fully of the ancestry connected to the surname. This phenomenon happens often in more mixed areas where there were many ethnicities from Europe that settled. Nowadays, it's starting to happen with the growing mixed race category of people in some areas of the US like on the east coast or the west coast.

Interesting. Possibly yes, Canarians could have something to do with the Puerto Rican sample too. But the Puerto Rican sample is pulled more toward Italy than the Cuban sample which is more toward the Portuguese, which I would think more Canarian blood would pull more toward Portugal, due to maybe the Cubans are more of a mix of Galician and Canarian. But I wonder what would make the Puerto Rican's pull more toward N. Italy. Possibly some admixed Corsican blood? There were many Corsicans that settled Puerto Rico as well. Interesting.

yes but as i sad puerto rican white sample is too small.

[Isleño]

yes but as i sad puerto rican white sample is too small.

Yes, of course that is a factor. But it would be interesting to understand the results of the Puerto Rican sample that is present, regardless of its size.

I could do the individual pca for puerto rico

Both Cubans and Puerto Ricans have significant Canarian genetic input, you should do one with Cubans, Puerto Ricans and Canarians on it.

That's one of the most interesting things I've noticed about the Puerto Ricans we've found on GEDMatch. There are a lot of people between 80-90% European, but very few above 90%.

Most of the 90%+ Euro people seem to be like my father and me (a mix of Recent Spanish and criollo Puerto Ricans)
