(a) Principal component analysis. The three-dimensional plot separates the individual pandas along three principal components. The affected females (red, band A) form one group whereas the unaffected male (blue, band B) and females (green, band C) are scattered. (b) Principal coordinates analysis. The three-dimensional plot separates the individual pandas along three principal coordinates. The affected females (red) form one group whereas the unaffected male (blue) and females (green) are scattered. The corresponding two-dimensional plots are shown in Fig. 5
