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.
