The Chilote is a horse breed which is isolated on the Island of Chiloe, off the coast of Chile. A total of 58 Chilote horses were genetically typed at 17 different loci; 7 of them belonged to blood group loci and were detected by standard hemagglutination and complement mediated hemolysis. The other 10 belonged to biochemical polymorphism detected by polyacrylamide and starch gel electrophoresis. Levels of genetic variability, estimated by measures of effective numbers of alleles and heterozygosity, were slightly above the mean of domestic horse breeds. There was no evidence of inbreeding and observed heterozygosity was greater than expected heterozygosity at 7 of 10 variable biochemical loci. Genetic markers present in the Chilote, suggest its relationship with horses from the Iberian Peninsula. Highest genetic similarity was with Andalusian and Peruvian Paso Breeds. Genetic variability would seem to indicate that this breed is in no immediate danger. However, the small size of the population indicates that the efforts for conservation in this special and unique type of pony should begin soon
