Fig. 2

Illustration of PCA for the 8 Nile tilapia populations depicted from principal component (PC) scores. a represents the PCA scatter plot, w1, and w2 depict wireframes for PC1 and PC2 respectively, demonstrating deformations for the major features behind the morph variations. Wireframe colours; light green and light blue, show the ideal shape and shape change respectively. Ellipses in the scatter plot represent a 95% confidence interval for the means. b and c depict PC1 and PC2 scores plotted on bar graphs respectively. Different superscript letters on the bar graphs indicate statistically significant Nile tilapia shapes (p < 0.05) and vice-versa
