Genetic variability of the zebu cattle breed (bos indicus) in the departament of huila using microsatellite molecular markers

Abstract

The polymorphism of 11 microsatellites from Zebu cattle (Bos indicus) were studied using a commercial multiplex system, to estimate genetic variability. Allele frequencies, polymorphism information content and heterozygosis were calculated. Allele frequencies revealed that in the sample analyzed the markers were not equally polymorphic. The average allele was 14.2 with the highest values for the TGLA122 microsatellites. The mean heterozygocity was 0.7056 and the polymorphism information content was 0.668. This multiplex analysis could be used for pedigree information and for adequate genetic improvements in breeding programs.
