Multifactorial analysis of Pisum diversity. For the entire data set the fraction of shared alleles for all pair-wise combinations of samples is analysed by multidimensional scaling. The output for the first two dimensions (explaining 5.32% and 2.99% of the variation are shown (see text). A: All points are plotted with each sample is colour-coded according to its corresponding sub-group membership. B: The mean of all values for each sub group, together with standard deviations are plotted. Sub Groups are colour coded as shown below. The subgroups of Group 1 lie so close together that they are not individually identified but collectively represented in red. All points are plotted in grey and the axes are removed for clarity.
