The patterns of admixture, divergence, and ancestry of African cattle populations determined from genome-wide SNP data

BMC Genomics, 2020
Background Humpless Bos taurus cattle are one of the earliest domestic cattle in Africa, followed by the arrival of humped Bos indicus cattle. The diverse indigenous cattle breeds of Africa are derived from these migrations, with most appearing to be ...
