Abstract

BUSTAMANTE, ANA V et al. Analisis of genetic diversity in three llama (Lama glama) populations from north-western Argentina. Rev. chil. hist. nat. [online]. 2006, vol.79, n.2, pp.175-184. ISSN 0716-078X.  http://dx.doi.org/10.4067/S0716-078X2006000200004.

The current genetic variability of three llama (Lama glama) management units from the northwestern Argentine (NOA) was analyzed. The troops, originally comprised a unique population that 10 years ago was divided into the current three. The DNA of 77 animals was studied by PCR amplification of 12 loci using microsatellite primers specific of Lama glama. A high level of genetic variability is sustained by the finding of one hundred and forty total alleles, a range of 9 to 16 allele number per locus and observed and expected hetrozygosities per locus varying from 1 to 0 and 0.9 to 0.47, respectively. Distributed within the three troops 44 private alleles were detected and proposed for uses such as to exchange new allelic variants. Hardy Weinberg Equilibrium test for each locus within each population showed significant deviation (P < 0.05) due to heterozygotes deficiency which may obey to the natural polygynic behaviour of the species. A moderated genetic differentiation between populations (Fst = 0.076; P = 0.000) may be explained by the introduction of foreing males parents at the moment of the original population subdivision. Transference to breeders of the data here obtained may be important in future management programmes
