Resumen

Two sub populations of the Canaria breed of cattle located in the islands of Gran Canaria and Tenerife were genetically studied. Six microsatellites markers have been analyzed in a total of 35 individuals distributed in different non related herds. All the analyzed markers were polymorphic, the number of alleles varied between two and eleven per locus. The variability, heterozigosity per locus and over all mean were estimated by mean of calculation the allelic frequencies. These results are indicative of the genetic variability present; although it is indispensable to enlarge the number of loci with the purpose of defining with more precision the situation of the breed.
