text: According to genetic tests, the most prevalent DNA marker found in all people of the continent (including Whites and mixed peoples) is a marker for Iberian genes (Portuguese and Spaniard). After Iberian (i.e.Lusitanian, Galician, Castilian and Catalan), the main European ethnicities are Italian, German and Slavic, followed by French and Dutch.
  Brazil has 31 million Italians and Argentina 20, Uruguay, Venezuela, Peru, Chile, Colombia and Ecuador also have considerable Italian diasporas. Brazil has 15.7 million Germans, Austrians, Luxembourgers and Swiss (second largest German diaspora after US) and Argentina 3.5 million consisting mostly of Russian Volga Germans. Other German groups can be found in Chile, Bolivia (mostly Mennonites), Paraguay (mostly German-Brazilians but including Mennonites), Peru, Uruguay and colonies in Venezuela.
  Brazil has the largest Slavic population with the number of Poles reaching 3 million people, followed by Ukrainians and Russians but comprising many other nationalities. Argentina following with the second largest number of Slavs, comprises a sizeable Croatian population, although Chile's Croatian community is the largest outside Croatia.
  Brazil has the largest Dutch and Scandinavian (mostly Norwegian) populations as well as the largest Lithuanian diaspora outside Baltic states. A small number of Boers or White Afrikaners migrated to South America during the 20th century, heading especially to Argentina and Brazil. And Lithuanian refugees fleeing the Nazi invasion and Soviet annexation in WW2 also formed communities in Colombia and Venezuela.
