STRUCTURE, NJ tree and network analyses detected the same three main populations as well as the two subpopulations (A and B) in the North Ethiopia/Sudan population and the four clusters; Konso, Negele Borena, Kenya and KO+KE+NB; in the South Ethiopia/Kenya population. The reticulate patterns seen in the network indicates either hybridization or recombination events between similar or closely related genotypes. The putative hybrid genotypes are indicated by a red bar line on the top. They are located in between their hypothetical parental strains in NE/SD-A subpopulation A and in cluster B1 of the NE/SD subpopulation B.
