Taurine–zebu admixture and genomic introgression in hybrid African cattle. a Interpolated synthetic map illustrating spatial distribution of admixture, which is generated from the first principal component (PC1) of a principal component analysis (PCA) of genetic variation across African cattle populations (modified with permission from [205]). b Genetic structure plot generated from high-density SNP data (Illumina BovineHD BeadChip with 777,962 SNPs) showing individual animal proportions assuming two source populations (N’Dama, n = 24; East African Zebu, n = 92; Nellore, n = 34) (the authors, unpublished results). The structure plot was generated using fastSTRUCTURE [270] and visualised using DISTRUCT [271]. c Chromosomal local ancestry plot for bovine chromosome 7 (BTA7) showing Bos taurus and Bos indicus ancestry in East African Zebu cattle (the authors, unpublished results). Nuclear oxidative phosphorylation (OXPHOS) genes are highlighted, illustrating the potential of admixed cattle for evaluating mitonuclear disequilibria. The plot was generated using the efficient local ancestry inference (ELAI) method [272]
