Pedigree and group differentiation between LW and LU. (A) Principal component analysis results of LW, LU, YS, LR and DU pig breeds. Blue, orange, red, pruple and green markers represent LW, LU, YS, LR and DU pigs, respectively. (B) Ancestry composition results with the assumed number of ancestries at K = 2. K is an adjustable parameter representing the number of possible ancestral varieties. Through the calculation of the cross validation error, we obtained K = 2 as the best K value. (C) Manhattan plot based on Fst of LW and LU.
