Colour pattern specification in the Mocker swallowtail Papilio dardanus: the transcription factor invected is a candidate for the mimicry locus H.

ABSTRACT: The swallowtail butterfly, Papilio dardanus, is an iconic example of a polymorphic Batesian mimic. The expression of various female-limited colour forms is thought to be controlled by a single autosomal locus, termed H, whose function in determining the wing pattern remains elusive. As a step towards the physical mapping of H, we established a set of 272 polymorphic amplified fragment length polymorphism (AFLP) markers (EcoRI-MseI). Segregation patterns in a 'female-informative' brood (exploiting the absence of crossing over in female Lepidoptera) mapped these AFLPs to 30 linkage groups (putative chromosomes). The difference between the hippocoon and cenea female forms segregating in this family resides on a single one of these linkage groups, defined by 14 AFLPs. In a 'male-informative' c
