This paper investigates the genetic diversity of one llama (Lama glama) and two guanaco (L. guanicoe) populations in Argentina by the analysis of six dinucleotide microsatellite loci markers derived from llama. Population parameters of the used markers such as allele size and distribution, mean heterozygosity, Hardy-Weinberg equilibrium, and population genetic distances were calculated, as well as polymorphic information content (PIC) and exclusion probability (EP). The camelid populations showed high mean heterozygosities and gene diversity values, with little differences between them, in concordance with the observed non-deviation from Hardy-Weinberg equilibrium. Among the total alleles, the analysis showed 25 (45%) private alleles in guanaco and 16 (36%) in llama. The results indicated that the investigated populations have high genetic variability and would be suitable as genetic stocks for conservation and sustainable utilisation programmes.
