我们对属于 6 个西班牙品种的 60 只山羊的线粒体高变区 1 (HVR1) 进行了部分测序。对这些序列和之前发表的序列的分析揭示了伊比利亚半岛品种的系统发育地理学结构较弱。来自单一品种的个体不会聚集成一个簇。此外，在 UPGMA 分析后，来自不同品种的个体通常共享单一的系统发育树分支。这可能反映出由于传统的季节性畜牧业和每年的长途迁徙，品种隔离并不存在。发现了三只属于 C 母系谱系的山羊，表明该谱系的分布范围比之前认为的更广泛。
We partially sequenced the mitochondrial hypervariable region 1 (HVR1) in 60 goats belonging to six Spanish breeds. The analysis of these and previously published sequences reveals a weak phylogeographical structure in the Iberian Peninsula breeds. Individuals from a single breed did not group into a single cluster. Furthermore, individuals from different breeds often shared single phylogenetic tree branches after UPGMA analysis. This could reflect the non-existence of breed isolation because of traditional seasonal pastoralism and annual long-distance migrations. Three goats belonging to the C maternal lineage were found, demonstrating a wider than previously thought distribution for this lineage.
