印度次大陆拥有 20 个特征明确的山羊品种，它们在生产牛奶、肉类和纤维方面的遗传潜力各不相同；抗病性；耐热性；和繁殖力。印度山羊占世界山羊种群的 20%，但尚未对这些具有重要经济意义的动物进行广泛的研究。因此，我们利用 HVRI 地区的 mtDNA 序列数据对来自印度不同地理区域的 10 个不同品种的 363 只山羊进行了目前的调查。我们在印度山羊中找到了种群结构和新谱系的证据，但无法将主要谱系中发现的遗传多样性与一万年前从单一线粒体DNA祖先开始的驯化相协调。因此，我们提出了家山羊的更复杂的起源。
The Indian subcontinent contains 20 well-characterized goat breeds, which vary in their genetic potential for the production of milk, meat, and fibre; disease resistance; heat tolerance; and fecundity. Indian goats make up 20% of the world's goat population, but there has been no extensive study of these economically important animals. Therefore, we have undertaken the present investigation of 363 goats belonging to 10 different breeds from different geographic regions of India using mtDNA sequence data from the HVRI region. We find evidence for population structure and novel lineages in Indian goats and cannot reconcile the genetic diversity found within the major lineage with domestication starting 10,000 years ago from a single mtDNA ancestor. Thus, we propose a more complex origin for domestic goats.
