For example the portion of a leaf eaten by an insect is a joint phenotype of the plant and the insect and the amount of food obtained by an offspring can be joint trait with its mother. Here I describe the evolution of joint phenotypes in quantitative genetic terms. A joint phenotype for multiple species evolves as the sum of additive genetic variances in each species, weighted by the selection on each species.
