FIGURE 7.

Shape differences between groups, and effects of hybridization between Balan laboratory offspring and Swiss mice. Group mean shapes are depicted from left to right (grey meshes); from top to bottom, the three molar descriptors. Colored meshes represent the change from one mean shape to another. Blue areas indicate compression and red expansion; all meshes to the same color scale for a given molar descriptor. Dominance and transgression value characterizing hybrids are given [Colour figure can be viewed at wileyonlinelibrary.com]
