Similarities and Differences between for Crescent Pond and Little Lake F2 Hybrid P-matrices
The PCA visualization of F2 hybrid P matrices shows a large amount of overlap between populations suggesting that their P matrices are quite similar (Figure 8). This interpretation is supported by a large estimate of PCA similarity between the two populations (~0.83), and the relative similarity in mean squared correlation, autonomy, and integration between populations (Appendix Tables C1 & C2). Despite this overall appearance of similarity there are still some distinct differences between populations. For instance, variation in the P-matrix of Crescent Pond aligns very closely with PC axis 2 while variation in the Little Lake P-matrix is uniformly distributed across PC1 and PC2 (Figure 8). Furthermore, we found smaller estimates of respondability (Crescent Pond: 0.022, Little Lake: 0.045) and flexibility (Crescent Pond: 0.58, Little Lake: 0.62) for the Crescent Pond P matrix compared to the Little Lake P matrix (Appendix Table C2). Together this suggests that there are unique relationships between traits in Crescent Pond and Little Lake.
