Plots showing results for signatures of selection. Venn diagram shows the unique and the shared PSGs identified in candidate regions under selection by both PBS and SweeD in Nigerian cattle (a). An amount of 2613 and 179 PSGs refer to the private genes detected by PBS and SweeD, respectively. And 61 PSGS are the common genes in both PBS and SweeD. Overlap of PSGs between African human, cattle (Nigerian cattle and N’Dama) and dog populations (b). The PSGs in African human, N’Dama, and dogs except the Nigerian cattle, were adopted from published publicly available datasets [42,43,44]. For Nigerian cattle the uniquely detected PSGs by PBS and SweeD combined together (a total of 2792 genes) excluding the 61 common genes were used. This information is described elsewhere in the results section and in the legend part (a). Manhattan plot indicates the autosomal genomes in Nigerian cattle generated by SweeD (c). The functional enrichment results of the overlapping PSGs between African human, cattle, and dog populations (d). Here, the gene ontology (GO) display three categories of biological function namely: MF, molecular function; BP, biological processes; and CC, cellular components [75]. Additionally, KEGG, Kyoto Encyclopedia of Genes and Genomes biological pathways were also integrated [76]
