Departamento del Cauca, mezcla, variantes genéticas

Resumen

La población actual del departamento del Cauca es el resultado de la mezcla de tres poblaciones parentales (europea, amerindia y africana). En este estudio se determinó la composición genética de 306 residentes del departamento mediante la utilización de 34 variantes autosómicas, 9 variantes en el cromosoma X, 6 en el ADNmt y 8 en el cromosoma Y. Los análisis de las variantes autosómicas y del cromosoma X revelaron que la población europea y la amerindia han contribuido en mayor proporción al actual acervo genético de la población estudiada. Los resultados de las variantes en el ADNmt y del cromosoma Y sugieren un fuerte sesgo sexual (flujo génico asimétrico) en el proceso de mezcla, en el que los cruces interétnicos fueron principalmente entre los colonizadores europeos y las mujeres nativas.
