Preliminary studies of the genetic structure of “Cimarron uruguayo” dog using microsatellite markers

Abstract

Objetive. To analyze the population structure, using microsatellite markers in a sample of “Cimarron Uruguayo” dogs. Materials and methods. Thirty dogs were analyzed in different areas of Uruguay with a set of nine molecular microsatellite markers using PCR. The population structure was analyzed using the free distribution software “Structure’’. Results. According to our data, the preliminary results show that it is not possible to establish a subdivision among the animals in the sample. Conclusions. The study supports the hypothesis that the currently existing canines derive from a founding nucleus that took refuge in the Northeastern region of the country. The distribution of the breed among the different areas of Uruguay continues nowadays, so there is no isolation among the different groups of animals, and the exchange is constant
