Resumen
One of the ways used today to human groups describe the characterization of genetic markers. These genetic markers identify human or allow us to differentiate between indigenous communities and give us clues as to the ancestors of today's communities are groups.
Most used markers to study the genetic structure of populations, easy and economic analysis, are blood groups. Being the most common ABO and Rh, known worldwide, are excellent system to understand the characteristics of human populations and to infer about their relationships with other related groups.
Nowadays there are few studies on the distribution of antigens and antibodies of the ABO system in the original peoples of Bolivia. It was evident that the ethnic Weenhayek 100% of the population belongs to blood group O and having a total absence of blood group A and B. This fact confirms the presence of an ethnic group with little or no contact with other cultures, polymorphism in the ABO system is scarce.
In Weenhayek ethnicity 100% of the population is positive for the antigen (D) Rh, which corroborates the low polymorphism for the Rh system in this ethnic group. This research confirmed by the determination of erythrocyte antigens ABO and Rh systems the low polymorphism in Weenhayek ethnicity, that despite the frequent invasions, migrations and settlements, this ethnic group maintains its low polymorphism, like many other ethnic groups living along the Bolivian territory.
