非洲畜牧业的遗传历史是有争议的，人们对其了解甚少。我们揭示了它的起源，二次运动和分化的遗传特征，通过研究15个微卫星位点在50个土著牛品种跨越目前在非洲的牛分布。最早的牛起源于非洲大陆，但近东和欧洲的遗传影响也被确定。非洲牛的最初扩张可能来自一个单一的起源地区。它到达大陆的南部是沿着东部路线而不是西部路线。B。indicus的遗传影响显示了通过非洲之角和非洲东海岸的主要入口点和两种渗入非洲大陆的模式。
The genetic history of African cattle pastoralism is controversial and poorly understood. We reveal the genetic signatures of its origins, secondary movements, and differentiation through the study of 15 microsatellite Loci in 50 indigenous cattle breeds spanning the present cattle distribution in Africa. The earliest cattle originated within the African continent, but Near East and European genetic influences are also identified. The initial expansion of African Bos taurus was Likely from a single region of origin. It reached the southern part of the continent by following an eastern route rather than a western one. The B. indicus genetic influence shows a major entry point through the Horn and the East Coast of Africa and two modes of introgression into the continent.
