Long description

This figure is a plot of average value of beak depth in offspring against average value of beak depth in parents, measured in millimetres. The axes are labelled from 7 to 12 millimetres, with beak depth values ranging from 7.5 to 11 mm in both groups. A line of best fit is drawn through the numerous data points. The figure shows a strong positive correlation between beak depth in offspring and parents.
