ABSTRACT

The polymorphism of 13 genetic markers in three racial groups (whites, mulattoes and blacks) of the population of Pinar del Río province (Cuba) were investigated. Differences among phenotypic rates in 8 of the 13 markers studies was found. The allelic frequencies in the markers that showed differences were highly significant among the racial groups. The loci investigated are able to clearly differentiate one racial group from another. This finding confirm the presumption that the population of this region is not homogeneous.


En este estudio se investigó el polimorfismo de 13 marcadores genéticos en tres grupos raciales (blancos, mulatos y negros), de la población de la provincia de Pinar del Río (Cuba). Se encontraron diferencias en las tasas fenotípicas en 8 de los 13 marcadores estudiados. Las frecuencias alélicas en los marcadores que mostraron diferencias fueron altamente significantes entre los grupos raciales. Los loci investigados son capaces de diferenciar claramente a un grupo racial de otro. Este hallazgo confirma la premisa de que la población de esta región no es homogénea.
