From: Shape based assignment tests suggest transgressive phenotypes in natural sculpin hybrids (Teleostei, Scorpaeniformes, Cottidae)

Figure 2

Extreme phenotypic values indicate a hybrid shape component. BI Hybrids are, on average, not intermediate along the third CV axis and may occupy extreme values relative to their parental populations. The parental populations as well as stream Naaf sculpins display little differentiation along the third CV axis. An inclusion of this hybrid specific shape component in distance based assignment increases the power to correctly identify hybrids more than two fold.
