Genetic Variability of Guzerat and Senepol Bovine Breeds by Microsatellite Markers

Bovine production plays economic importance in Brazil and Guzerat and Senepol breeds are producer of meat. Itwas aimed to analyze the genetic variability of Guzerat and Senepol breeds by microsatellite markers. The breedswere collected and genotyped for ten microsatellite loci by automatic sequencer and statistically analysed. A total of53 alleles were observed being the average number was 5.3 in both breeds. The effective numbers of alleles were3.36 for Guzerat and 3.11 for Senepol cattle. The Shannon indexes were 1.36 for Guzerat and 1.26 for Senepolcattle. The expected heterozigosity were 0.71 and PIC values were 0.64 in both breeds. The FIS were 0.01 and 0.11for Guzerat and Senepol breeds, respectively and Hardy-Weinberg equilibrium were P>0.05 for Guzerat andP
