Developmental regulation of caste-specific characters in social-insect polyphenism.

abstract：:The mocker swallowtail, Papilio dardanus, has a female-limited polymorphic mimicry. This polymorphism is controlled by allelic variation at a single locus with at least 11 alleles. Many of the alternative morphs are accurate mimics of different species of distasteful butterflies. Geneticists have long been interested ...
