Abstract The genetic diversity and structure of Bolivian alpaca populations, and genetic relationship between alpacas, llamas and vicunas has been assessed using microsatellite markers. Overall alpaca and llama populations present higher genetic diversity (He = 0,73) than vicunas (He = 0,59). Genetic analysis and population structure have shown a closer relationship between alpacas and llamas, suggesting admixture at productive systems where alpacas and llamas are raised together. Alpaca productive systems have shown low differentiation values (FST = 0,026), and have been clustered into five inferred groups. Populations with higher contribution to total genetic diversity were Ulla Ulla and Catacora. These data could stablish a base line for management and conservation of alpaca populations, particularly to avoid hybridization with llamas, which may affect fiber quality, and to maintain current genetic diversity levels at the Bolivian productive systems.

玻利维亚羊驼种内遗传分析及与美洲驼和骆马的种间关系

摘要 利用微卫星标记对玻利维亚羊驼种群的遗传多样性和结构以及羊驼、美洲驼和骆马之间的遗传关系进行了评估。总体而言，羊驼和美洲驼种群的遗传多样性 (He = 0,73) 高于骆马 (He = 0,59)。遗传分析和种群结构表明羊驼和美洲驼之间的关系更密切，这表明在羊驼和美洲驼一起饲养的生产系统中混合。羊驼生产系统显示出低分化值 (FST = 0,026)，并被分为五个推断组。对总遗传多样性贡献较高的种群是 Ulla Ulla 和 Catacora。这些数据可以确定管理和保护羊驼种群的基线，特别是避免与美洲驼杂交，
