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.

Interestingly, doublesex turned out to be the primary gene associated with mimetic wing patterns, further implicating the pivotal role of the gene in mimicry. Click here to sign up.

Sex-limited mimicry is phylogenetically widespread in the swallowtail butterfly genus Papilio, in which it is often associated with female mimetic polymorphism.

Skip to search form Skip to main suprgene. Neither of the above. Summing up, doublesex in P. Recommend to your librarian. For this experiment, we used Only results for forewing and abdomen are shown We designed PCR primers for partially overlapping products spanning the because hindwing expression mirrors forewing expression. Received doublese November ; accepted 30 January By expressing different versions of the gene at different levels, the butterflies can radically switch their wing patterns to ia many different species.

The variant call format and VCFtools. They zeroed in on five genes that seemed to be eligible candidates controlling wing pattern variation.

Monarch Butterfly Conservationist Dies. We extracted total RNA using Trizol and gener- The authors further simulated structures of the doublesex proteins in mimetic and non-mimetic female forms and found them to be substantially different. They envisioned this supergene as a cluster of tightly-linked genes located near each other and capable of functioning together as a single genetic unit.

Cell— Dmrt genes in the development and evolution of sexual dimorphism.


This has led to sexual dimorphism marked differences in gender in many mimetic species. The genetics of polymorphism in the Lepidoptera. First, although we found many mutations in 1 2 3 F2 1.

In multiple polymorphic species, the entire wing pattern phenotype is controlled by a single Mendelian ‘supergene’. Protein structure prediction on the Web: Developmental perspectives on evolution of butterfly mimicry.

The authors hope to examine similar instances of polymorphism in other butterflies to determine whether doublesex or other genes act as mimicry supergenes.
