Fig. 4From: Polyploidy and the relationship between leaf structure and function: implications for correlated evolution of anatomy, morphology, and physiology in Brassica Cluster analysis of the bivariate relationship between Fo and Fs for diploid parent and allotetraploid hybrid species indicates that the three apparent clusterings of data (cluster 1, circles; cluster 2, crosses; and cluster 3, triangles) is not attributable to individual species (designated by color).
