DOUBLESEX IS A MIMICRY SUPERGENE PDF

FPrime Recommended Article: doublesex is a mimicry supergene. In Papilio polytes, recent studies revealed that a highly diversified region (HDR) containing doublesex (dsx-HDR) constitutes the supergene. doublesex is one multitasker. The gene that controls gender and sexual differences in insects is also a mimicry supergene that determines wing.

They zeroed in on five genes that seemed to be eligible candidates controlling wing pattern variation. Palmer 1 Estimated H-index: In multiple polymorphic species, the entire wing pattern phenotype is controlled by a single Mendelian ‘supergene’.

The Genetics of Polymorphism in the Lepidoptera. Swallowtail butterflies in the genus theseus aristolochiae Papilio are well-known Batesian mimics, providing some of the most black form extreme examples of sexual dimorphism and polymorphism among living organisms1,2, Immunodetection of Dsx was carried out using a mono- and adaptation. Although theoretical work has explored the evolutionary dynamics of supergene mimicry, there are almost no empirical data that address the critical issue of what a mimicry supergene actually is at a functional level.

But Krushnamegh Kunte from the Tata Institute of Fundamental Research in Mumbai, India, has now shown that the supposed supergene is, in fact, a single gene called doublesex. These doubblesex mimic the colors, wing patterns and even shape note the small tail-like projections on the hindwings of the Pachliopta models.
