Genética poblacional de cobayas de Colombia, Cavia spp. (Rodentia: Caviidae) con marcadores moleculares RAPD

En el presente estudio mostramos los primeros resultados moleculares de formas colombianas de Cavia. Claramente, la poblacion silvestre de C. anolaimae fue geneticamente diferenciada de la forma domestica, C. porcellus, tal como ha sido demostrado por otros autores utilizando resultados morfometricos, osteologicos y cariotipicos. Ambas especies mostraron un considerable nivel de diversidad genetica, aunque el segundo taxon mostro niveles mayores de esta diversidad. Los niveles de heterogeneidad genetica tambien fueron mayores entre las poblaciones de C. porcellus (FST=0.254) que entre las poblaciones de C. anolaimae (FST=0.118). Esos niveles significativos de heterogeneidad genetica, y los consiguientes bajos niveles de flujo genico, fueron discutidos comparativamente con los resultados por otros autores analizando otros marcadores moleculares (citocromo-b mitocondrial). Los resultados aqui mostrados son coherentes con un complejo proceso de domesticacion en Cavia porcellus.
