["Cholos de Coclé": determination of their racial mixture and genetic origins].

: We have found, in this first genetic study of a supposedly admixed Panamanian population, that the cultural group known as "cholos of Cocle" constitute a trihybrid mixture, whose genetic pool has the following composition: 44% Amerindian, 38% Caucasoid and 18% Negroid. Similarly, we have detected Amerindian genes, such as LDHB--Gua and TFchi, in proportions that relate this population with the extant Ngawbe (Guaymi). Nevertheless, the very high frequency of variant PEPA--KUN seems to indicate the genetic contribution of Amerindian populations from Eastern Panama, possibly from the extinct indigenous group cueva. This variant is frequently found among the present-day Kuna, but has not been detected among Nagawbe and Bugle.
