It is estimated that in Chile 10% of the population has Rh Negative blood. Very few of them have any idea of their blood group, which becomes a problem for Blood Banks, who must provide blood in the event of an accident or illness.
While some regions with native populations tend to have percentages below 1%, others seem to hover around 20%.
Native American populations tend to be predominantly of type O blood while those of Basque descent have significant percentages of type A blood.
Over the past 12 years, the following group has been very helpful towards Rh negatives in Chile:

DID YOU KNOW?
The Basque presence in Chile began in the Conquista period, for in the armies of the first colonizers came an important number of soldiers from the Basque Provinces and from Navarra. In the 16th century, of the 157 Peninsular families that settled in Chile, 39 had Basque surnames. This number progressively grew, as reflected in the number of governors of Basque origin.
Forms a regional immigration corridor between Spain and Chile, one that is large, visible, and continues over time. Basque immigration can be divided into historical periods: discovery, foundation, and colonial period; the wave of immigration of the 18th century; and the recent immigrants (19th and 20th centuries).
During the 18th century, the country experimented a mass immigration coming from the Basque provinces and Navarre, by the end of the 18th century represents 27% of the Chilean population.
An estimated 1.6 million (10%) to 4.7 million (30%) Chileans have a surname (one or both) of Basque origin. This figure is to the least as the number of Basque descendence is great and plentiful. If one were to compare the large wave of Basques that fled to the population in the Basque Country you can see that in a way ethnically speaking Chile has more Basque blood than the country of origin.
The linkage between ABO blood group, ethnicity and geography is fascinating. I am not convinced that it always holds true. In my individual case, I am B Negative. My type B is not inherited in my direct patrilineal line. It comes in from my paternal grandmother’s lines. That fits with the known global distribution of blood group B, and its clinal dispersion in earlier days. My grandmother’s line came to England from Eastern Europe, and so the individual history matches the broader demographic data. Blood type A is common in Armenia, and among Armenians worldwide. There is a credible body of thought (not genetic and not blood type based) that claims a historical link between Armenia and the Basques. Both have high percentages of blood group A.
Could the link be a common ancestry between Basques and Armenians rather than Basques descending from Armenians?
Certainly possible. A key problem with ancient population analysis is that there are multiple migrations and back-migrations.
The French people in south Louisiana were 20,% rh- less than 80 years ago before the oil boom here.. I’m O- and DNA testsays I’m 91%French and the map provided it
showed the area in south France..
