Figure 5

Scatter plots of mid-parent (x axis) and mid-offspring (y axis) values for (a) leaf length, (b) leaf width, (c) leaf shape (leaf length/leaf width) and (d) petiole length from 33 independent crosses involving 66 randomly paired adults of all phenotypes at the study site. Weighted linear regressions: leaf length: F_{1, 31}=18.85, P<0.001, R²=35.81; leaf width: F_{1, 31}=5.68, P=0.023, R²=12.76; leaf shape: F_{1, 31}=21.17, P<0.001, R²=38.66; petiole length: F_{1, 31}=17.60, P<0.001, R²=34.15.
