Population genetic structure and relationship of the African, South Asian, Middle Eastern, European, and wild Bezoar goat populations. (a) PCA, (b) ADMIXTURE analysis at K = 2, 3, 4, and 5, (c) Cross-validation error (CV) value at K = 4, (d) phylogenetic tree constructed using FST values, (ea and eb) the pattern of linkage disequilibrium (r2) from 0 to 1 Mb and (fa and fb) the pattern of effective population size (Ne) in the past 1000 generations. Note: The LD and Ne are plotted based on the admixture, PCA and phylogenetic tree results. Ethiopian-A includes Abergelle, Gonder, Agew, Ambo, Gumuz, Arsi-Bale and Keffa whereas Ethiopian-B consists of Afar, Short ear Somali, Long ear Somali, Haraghe highland, Woyto-Guji and Kenyan-Boarn goats.
