Diversity of African cattle and gene flow between cattle populations. The genetic diversity estimated by nucleotide diversity index (Pi) in non-overlapping windows of 100 kb window size (a). Pattern of population splits and migration between Nigerian and other cattle populations (b). The tree shows migration or evidence of gene flow from other populations particularly the N’Dama breed into the gene pool of Nigerian cattle population. Boran, Kenana, Ogaden represent East African zebus; N’Dama, and Muturu represent the African taurine and Ankole also known as Sanga breed, is the hybrid between African zebu and taurine; pure zebu and Asian crossbred represent cattle from Asia and East Africa; the Holstein breed stands as the only European taurine cattle used in this study; and Nigeria represent cattle sampled in Nigeria; B. bubalis is the outgroup (more details are given in Additional file 1: Table S2)
