Shape and size differences between the upper jaw skeletons of CA, DC and F1 hybrids. a Camera Lucida drawing of CA upper jaw indicating anatomical landmarks. b CV1 deformation vectors on CA landmark configuration. c Mean and distribution of CA (n = 15), DC (n = 12) and F1 (n = 16) individuals along the CV1 axis, expressed in within-species standard deviation units. **p < 0.001, Bartlett’s test. df Dissected, alizarin red-/alcian blue-stained upper jaw skeletons of CA (d), DC (e) and F1 (f) specimens. Scale bar 2.5 mm. gi Mean and distribution of the CA, DC and F1 premaxillary ascending process length (g), premaxillary dentigerous process length (h) and premaxillary process angle (i). ***p < 0.001, Tukey’s HSD test. Bone nomenclature after [64]. MX maxilla, P palatine, PMX premaxilla
