Figure 1.
Size sexual dimorphism in the PW Dog. Forty two skeletal metrics were corrected to a mean of 0 and a standard deviation of 1. A matrix composed of the corrected skeletal metrics of 463 dogs was used to calculate the Principal Components of skeletal variation. Size is represented by values of PC1 calculated using the Pearson correlation option of XLSTAT (http://www.xlstat.com) for 42 skeletal metrics (males♦; females □).
