Outline of Final Research Achievements

Papilio memnon exhibits a female-limited Batesian mimicry polymorphism, an intriguing system for investigating the maintenance of genetic polymorphisms: females display both mimetic and non-mimetic forms, whereas males are uniformly non-mimetic. This polymorphism is thought to be maintained by negative frequency-dependent predation, but no comprehensive investigations have been conducted. We identified two allelic sequences of the putative control gene, doublesex, that directly corresponded with the mimetic and non-mimetic female phenotypes in P. memnon. The mimetic allele of doublesex gene persisted at intermediate frequencies at a site in Taiwan, and an equivalent reproductive performance of the two forms over time suggested that negative frequency-dependent selection (NFDS) contributed to the mimicry polymorphism. In a laboratory test for physiological cost of mimetic genotypes, we found no evidence that physiological costs were associated with the mimetic genotypes.
