Evolutionary variation in gene expression is associated with dimorphism in eusocial vespid wasps.

Abstract excerpt

Phenotypic diversity is frequently generated by differences in gene expression. In this study, we addressed the relationship between homology in gene expression and phenotype among four species of eusocial wasps. Specifically, we investigated the evolution of caste-specific and sex-specific gene expression patterns associated with caste polyphenisms and sexual dimorphisms. We also identified several genes with...
