ABSTRACT
The genetic variability within the Uruguayan Creole horse and its relationship to a group of geographically or historically related breeds (Spanish Pure-bred, Barb, Quarter horse, Paso Fino, Peruvian Paso, Arabian and Thoroughbred horse), was evaluated using 25 loci (seven of blood groups, nine of protein polymorphisms and nine microsatellites) analyzed on a total of 145 Uruguayan Creole horses. In this study, blood group and protein polymorphism variants that are considered to be breed markers of Spanish Pure-bred and Barb horses were detected in the Creole breed. Conversely, some microsatellites and protein polymorphisms alleles were found uniquely in the Creole horse. American horse breeds together with Barb and Arabian horses clearly formed a separate cluster from the Spanish pure-bred and Thoroughbred breeds, as shown by an UPGMA dendrogram based on Nei's standard genetic distance. Data in this study provided evidence for considerable genetic variation within Uruguayan Creole horses and of a distinctive breed profile. Both traits were most likely inherited from the XVIth century Spanish horses, more closely related to Barb than to Spanish Pure-bred.
