Although genes have specific phenotypic consequences in a
given species, this functional relationship can clearly change
during the course of evolution. Many cases of evolutionary
dissociations between homologous genes and homologous
morphological features are now known. These dissociations
have interesting and important implications for understanding
the genetic basis for evolutionary change in morphology.

Introduction
One of the fascinating realizations to emerge during the
past two decades of developmental genetics is the extra-
ordinary complexity of the relationship between genotype
