ABSTRACT

Objective. To analyze the genetic variability in two populations of the native canine breed "Uruguayan Cimarron" from different areas of the country. Materials and methods. DNA was isolated from 40 animals of the Cimarron breed. Using PCR, 11 RAPD (random amplified polymorphism of DNA) molecular markers were analyzed. Results. 14.9% of loci were polymorphic. We found an index of shared bands of 0.91, a genetic distance of 0.16 and a Nei's average diversity index of 0.08. Conclusions. Both populations present a high homogeneity and genetic identity for these markers suggesting that they belong to a common genetic nucleus.


Objetivo. Analizar la variabilidad genética en dos poblaciones de caninos de la raza autóctona "Cimarrón uruguayo" provenientes de distintas zonas del País. Materiales y métodos. Se aisló ADN de 40 animales de la raza Cimarrón. Mediante la técnica de PCR se analizaron 11 marcadores moleculares RAPD (amplificación al azar de ADN polimórfico). Resultados. Se detectó un 14.9% de loci polimórficos. Se obtuvo un índice de bandas compartidas de 0.91, una distancia genética de 0.16 e índice promedio de diversidad de Nei's de 0.08. Conclusiones. Ambas poblaciones presentan una alta homogeneidad e identidad genética para estos marcadores y pertenecerían a un núcleo genético común.
