## Figure 5.
Standardized linear phenotypic selection gradient for a) the number of flowers and
b) floral morphology in a hybrid population of Orchis militaris and O. purpurea . The selection gradient is illustrated with an added-variable plot, in which the residuals
from a linear regression model of relative fitness on all traits except the focal
trait are plotted against the residuals from a regression model of the focal trait
on the other traits.
