Polyphenisms: a developmental perspective.

Abstract excerpt

Polyphenisms, the production of two or more discrete phenotypes from a single genome, are a remarkable reflection of the flexibility of developmental mechanisms. Examples of polyphenisms include castes in eusocial insects, and winged versus wingless forms of aphids. How the signals that drive these alternate forms are received and interpreted, and how they trigger different developmental trajectories remains...
