Thread: European admixture In Latinos

  1. #1

    European admixture In Latinos

    Someone In another forum collected thousands of gedmatch and did this study. What you think?

    For example approx 25-30% of Mexicans fall within 50-60% Euro range and 20% 70-100% European

    Any thoughts?

    Seems reasonable. In Brazil depends on the region and social class and we can find the biggest admixture because we can find the biggest and most complex population.

    I also I think for Mexico makes sense a perfect balanced mestizo country with European leaning minority and Amerindian.

    I would stick to the 23andMe studies and not Gedmatch, since Gedmatch is full of samples from the USA. From my observations, immigrants from the Caribbean and South America into certain areas like New York tend to have more European ancestry. The opposite may be true for immigrants from Mexico and Central America into the SW USA. Nothing scientific, but again, the Gedmatch samples may be skewing things.

    I partially agree with you because most southern American immigrants In U.S are middle class origin with college degrees .

    Also the majority of immigrants from Mexico has always been poor or working class but majority are decends of central regions.


    Lately a lot southern Mexican waves have been hiting the north east coast most of the time are from Indigenous communities such as Oaxaca or puebla where historically the mestizo waves has always been arriving the west coast/south west.

    These are interesting, and the graphs are fun. One problem with these studies though is that the samples are limited to test takers, so inevitably are a biased sampling. I find it hard to believe, for example, that the average Cuban is that overwhelmingly Southern European, as opposed to SSA (37-45% of the population identifies as mixed race or black according to statistics from the past two decades). If you look at Guyana, you can see that individuals of South Asian descent are probably somewhat over-represented. Likewise in Peru, I would imagine the Southern European to Amerindian ratio is somewhat skewed, since 86% of the population identifies as either Mestizo (60.2%) or Amerindian (25.75), and only 5.9% white according to the most recent census figures. We have to take into account that wealth and physical and social mobility play a role in terms of the types of people who have access to or interest in these tests.
