Principal components (PC) of the genetic relationship matrices for 116 WB (lower diagonal) and 36 CP (upper diagonal). Upper and lower diagonal plots show principal components analysis (PCA) biplots for CP and WB respectively, with colour designating the breed subtype and marker designating the sample origin. In CP: B principal component (PC) 1 by PC 2; C of PC 1 by PC 3; and F of PC 2 by PC 3; and in WB: D PC 1 by PC 2; G PC 1 by PC 3; and H PC 2 by PC 3. Diagonal plots are kernel density estimator plots illustrating the distributions of the principal components, with distribution curves for each breed subtype: distribution for both breed analyses is shown in: A PC 1; E PC 2; and I PC 3. The first three PC in CP explained 4.7%, 4.2% and 3.7% of variance respectively, and in WB explained 2.5%, 2.2% and 1.7% of variance respectively.
